Chapter 6: Q.26 (page 385)

In a normal distribution, x = 5 and z = 鈥�1.25. This tells you that x = 5 is ____ standard deviations to the ____ (right or left) of the mean.

Short Answer

Expert verified

In a normal distribution,x=5androle="math" localid="1648273503773" z=-1.25. This tells you thatx=5is1.25standard deviations to the left of the mean.

Step by step solution

01

Given Information 

Given in the question that, in a normal distribution, x = 5 and z = 鈥�1.25.

We have to fill the blanks with correct answer.

02

Explanation 

A Z-score means a numerical size that represents a value's association to the mean of a set of values.

By using the z-score it can be calculate that how many standard deviations, the value of xwill lie below (left) or above (right) the mean of the distribution.

From the information given in the question, we observe that the value of x=5and z=-1.25.

Suppose X ~ N(12, 6). What is the z-score of x = 2?

An expert witness for a paternity lawsuit testifies that the length of a pregnancy is normally distributed with a mean of 280days and a standard deviation of 13days. An alleged father was out of the country from 240to 306days before the birth of the child, so the pregnancy would have been less than 240days or more than 306days long if he was the father. The birth was uncomplicated, and the child needed no medical intervention. What is the probability that he was NOT the father? What is the probability that he could be the father? Calculate the localid="1653472319552" z-scores first, and then use those to calculate the probability.

Suppose X ~ N(2, 3). What value of x has a z-score of 鈥�0.67?

In 2005,1,475,623students heading to college took the SAT. The distribution of scores in the math section of the SAT follows a normal distribution with mean 碌=520and standard deviation 蟽=115

  1. Calculate the z-score for an SAT score of 720. Interpret it using a complete sentence.
  2. What math SAT score is 1.5 standard deviations above the mean? What can you say about this SAT score?
  3. For 2012, the SAT math test had a mean of 514 and standard deviation 117. The ACT math test is an alternate to the SAT and is approximately normally distributed with mean 21 and standard deviation 5.3. If one person took the SAT math test and scored 700 and a second person took the ACT math test and scored 30, who did better with respect to the test they took?
