Languages in Canada Canada has two official languages, English and French. Choose a Canadian at random and ask, 鈥淲hat is your mother tongue?鈥� Here is the distribution of responses, combining many separate languages from the broad Asia/Pacific region
a. Explain why this is a valid probability model.
b. What is the probability that the chosen person鈥檚 mother tongue is not English?
c. What is the probability that the chosen person鈥檚 mother tongue is one of Canada鈥檚 official languages?
Lefties A website claims that of U.S. adults are left-handed. A researcher believes that this figure is too low. She decides to test this claim by taking a random sample of U.S. adults and recording how many are left-handed. Four of the adults in the sample are left-handed. Does this result give convincing evidence that the website鈥檚 claim is too low? To find out, we want to perform a simulation to estimate the probability of getting or more left-handed people in a random sample of size from a very large population in which of the people are left-handed.
Let to indicate left-handed and to 99 represent right-handed. Move left to Page Number: right across a row in Table . Each pair of digits represents one person. Keep going until you get different pairs of digits. Record how many people in the simulated sample are left-handed. Repeat this process many, many times. Find the proportion of trials in which or more people in the simulated sample were left-handed.
Scrabble In the game of Scrabble, each player begins by randomly selecting tiles from a bag containing tiles. There are vowels, consonants, and blank tiles in the bag. Cait chooses her tiles and is surprised to discover that all of them are vowels. We want to perform a simulation to determine the probability that a player will randomly select vowels.
a. Describe how you would use a table of random digits to carry out this simulation.
b. Perform one trial of the simulation using the random digits given. Copy the digits onto your paper and mark directly on or above them so that someone can follow what you did.
c. In of the trials of the simulation, all tiles were vowels. Does this result give convincing evidence that the bag of tiles was not well mixed?
A basketball player claims to make of her shots from the field. We want to simulate the player taking sets of shots, assuming that her claim is true.
To simulate the number of makes in shot attempts, you would perform the simulation as follows:
a. Use random one-digit numbers, where are a make and are a miss.
b. Use random two-digit numbers, where are a make and are a miss.
c. Use random two-digit numbers, where are a make and are a miss.
d. Use random one-digit numbers, where is a make and are a miss.
e. Use random two-digit numbers, where are a make and are a miss.
