Exercises 33 to 35 refer to the following setting. A basketball player makes 47% of her shots from the field during the season. Use the correct choice from the previous question and these random digits to simulate 10 shots: 82734 71490 20467 47511 81676 55300 94383 14893 How many of these 10 shots are hits? (a) 2 (b) 3 (c) 4 (d) 5 (e) 6

Short Answer

Expert verified
The player hits 4 out of the 10 shots.

Step by step solution

01

Understand the problem

The problem involves simulating the basketball player's shots based on a percentage success rate, which is 47%. We are given random digits to use for this simulation.
02

Define the simulation method

To simulate whether a shot is successful, each simulated shot corresponds to a two-digit random number. If the number is 00 to 46, the shot is considered a hit because the player makes 47% of her shots. Numbers 47 to 99 mean the shot is a miss.
03

Pair the digits

The given sequence of random digits is 82734 71490 20467 47511 81676 55300 94383 14893. We need to pair these digits as follows: 82, 73, 47, 14, 90, 20, 46, 74, 75, and 11.
04

Determine hits and misses

Compare each paired number to the success range (00 to 46): - 82 (miss) - 73 (miss) - 47 (miss) - 14 (hit) - 90 (miss) - 20 (hit) - 46 (hit) - 74 (miss) - 75 (miss) - 11 (hit).
05

Count the number of hits

Among the paired numbers, we identified hits as the numbers 14, 20, 46, and 11. Therefore, we have a total of 4 hits.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Probability
Probability is a fundamental concept in statistics and mathematics. It is a measure that quantifies the likelihood of an event occurring out of the total possible outcomes. In this exercise, we examine the probability of a basketball player successfully making a shot from the field, which is given as 47%.
The probability can be expressed as a fraction, decimal, or percentage. Here, it is a percentage, as it makes the concept more relatable in practical terms. Therefore, when the player attempts a shot, there is a 47% chance, or probability of 0.47, that the shot will be successful.
This means, on average, if the player takes 100 shots, she is expected to make 47 of them. However, it's important to note that probability deals with the expectation rather than certainty, as real-life outcomes can vary due to randomness.
Success Rate Simulation
A success rate simulation is used to model real-world systems and predict outcomes. It enables us to understand how changes might affect results by artificially recreating the system or process with given probabilities.
In the basketball player's case, we know she has a success rate of 47%. The goal of the simulation is to determine how many successful shots would occur if she attempted 10 shots.
To achieve this, the simulation process involves using random numbers to represent potential shot outcomes. Each random number mirrors a possible reality, allowing us to predict the success of each attempt based on her historical success rate.
Simulation Method
The simulation method is an approach where random numbers are utilized to forecast possible outcomes in uncertain or random processes, like shooting a basketball. This technique involves mapping numerical ranges to different outcomes based on a known probability distribution, true in many statistical experiments.
In our problem, each shot's success is simulated by comparing paired digits to the success range defined by the player's probability. Since the player's success rate is 47%, the numbers 00 through 46 are allocated to successful shots, while 47 to 99 denote misses.
The pairing of random digits simulates each shot attempt. These pairs are systematically checked against the success range to determine whether each shot is successful. By doing this, we can simulate 10 shots and determine the number of hits.
Statistical Experiment
Statistical experiments involve experiments or interactions in which the outcome is uncertain. The basketball shot simulation is a quintessential example. Such experiments allow us to draw conclusions about a population or process based on sample data.
In this exercise, the step-by-step method embodies a statistical experiment, where paired random digits simulate actual shots. Each digit pair is treated as an observation in our experiment.
The randomness and variability introduced through this procedure can help us study how often an outcome—like successfully scoring in basketball—occurs. By repeating and analyzing the process, insights into more complex probability scenarios can be gained, offering profound implications for predictive modeling.

Genetics Suppose a married man and woman both carry a gene for cystic fibrosis but don’t have the disease themselves. According to the laws of genetics, the probability that their first child will develop cystic fibrosis is 0.25. (a) Explain what this probability means. (b) Why doesn’t this probability say that if the couple has 4 children, one of them is guaranteed to get cystic fibrosis?

The probability of a flush A poker player holds a flush when all 5 cards in the hand belong to the same suit. We will find the probability of a flush when 5 cards are dealt. Remember that a deck contains 52 cards, 13 of each suit, and that when the deck is well shuffled, each card dealt is equally likely to be any of those that remain in the deck. (a) We will concentrate on spades. What is the probability that the first card dealt is a spade? What is the conditional probability that the second card is a spade given that the first is a spade? (b) Continue to count the remaining cards to find the conditional probabilities of a spade on the third, the fourth, and the fifth card given in each case that all previous cards are spades. (c) The probability of being dealt 5 spades is the product of the five probabilities you have found. Why? What is this probability? (d) The probability of being dealt 5 hearts or 5 diamonds or 5 clubs is the same as the probability of being dealt 5 spades. What is the probability of being dealt a flush?

Drug testing Athletes are often tested for use of performance-enhancing drugs. Drug tests aren’t perfect—they sometimes say that an athlete took a banned substance when that isn’t the case (a false positive). Other times, the test concludes that the athlete is clean when he or she actually took a banned substance (a false negative). For one commonly used drug test, the probability of a false negative is 0.03. (a) Interpret this probability as a long-run relative frequency. (b) Which is a more serious error in this case: a false positive or a false negative? Justify your answer.

Free throws A basketball player has probability 0.75 of making a free throw. Explain how you would use each chance device to simulate one free throw by the player. (a) A six-sided die (b) Table D of random digits (c) A standard deck of playing cards

Get rich A survey of 4826 randomly selected young adults (aged 19 to 25) asked, What do you think are the chances you will have much more than a middle-class income at age 30?
