Chapter 6: Q6.16 (page 260)

Precisely, what is meant by the statement that a population is normally distributed ?

Short Answer

Expert verified

A population is normally distributed means it is evenly distributed around mean, its un skewed & measures of central tendency are same. Sample also follow same distribution.

Step by step solution

01

Normal Distribution Meaning 

Normal Distribution is a continuous distribution, non skewed & symmetrical around the mean.

02

Normal Distribution characteristics 

Characteristics of a normally distributed population are :

  • It is evenly distributed around the mean, with major data points near the centre & little outliers at the edges.
  • It is non skewed & symmetrical ; measures of central tendency ie mean, median, mode are equal.
  • Population follows normal distribution implies that aptly drawn sample also follows normal distribution.

Critical Values. In Exercises 41–44, find the indicated critical value. Round results to two decimal places.

In Exercises 7–10, use the same population of {4, 5, 9} that was used in Examples 2 and 5. As in Examples 2 and 5, assume that samples of size n = 2 are randomly selected with replacement.

Sampling Distribution of the Sample Proportion

a. For the population, find the proportion of odd numbers.

b. Table 6-2 describes the sampling distribution of the sample mean. Construct a similar table representing the sampling distribution of the sample proportion of odd numbers. Then combine values of the sample proportion that are the same, as in Table 6-3. (Hint: See Example 2 on page 258 for Tables 6-2 and 6-3, which describe the sampling distribution of the sample mean.)

c. Find the mean of the sampling distribution of the sample proportion of odd numbers.

d. Based on the preceding results, is the sample proportion an unbiased estimator of the population proportion? Why or why not?

In Exercises 5–8, find the area of the shaded region. The graphs depict IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15 (as on the Wechsler IQ test).

In Exercises 9–12, find the indicated IQ score and round to the nearest whole number. The graphs depict IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15 (as on the Wechsler IQ test).

Finding Bone Density Scores. In Exercises 37–40 assume that a randomly selected subject is given a bone density test. Bone density test scores are normally distributed with a mean of 0 and a standard deviation of 1. In each case, draw a graph, then find the bone density test score corresponding to the given information. Round results to two decimal places.

Find P99, the 99th percentile. This is the bone density score separating the bottom 99% from the top 1%.
