Chapter 7: Q. 28 (page 439)

The candy machine Suppose a large candy machine has 15%orange candies. Use Figure 7.13 (page 435) to help answer the following questions.

(a) Would you be surprised if a sample of 25 candies from the machine contained 8 orange candies (that's 32%orange)? How about 5 orange candies ( 20%orange)? Explain.

(b) Which is more surprising: getting a sample of 25 candies in which 32%are orange or getting a sample of 50 candies in which 32% are orange? Explain.

Short Answer

Expert verified

a. 8 orange candies: Surprising

b. 5 orange candies: Not surprising

Step by step solution

01

Given Information (Part a)

Large candy machine has =15%orange candies

Sample candies=25

Machine contained 8 orange candies(32%)

5 orange candies(20%)=?

Suppose we select an SRS of size n=100from a large population having proportion p of successes. Let p∧ be the proportion of successes in the sample. For which value of p would it be safe to use the Normal approximation to the sampling distribution of p∧?

(a) 0.01

(b) 111

(c) 0.85

(d) 0.975

(e)0.999

Dem bones (2.2) Osteoporosis is a condition in which the bones become brittle due to loss of minerals. To diagnose osteoporosis, an elaborate apparatus measures bone mineral density (BMD). BMD is usually reported in standardized form. The standardization is based on a population of healthy young adults. The World Health Organization (WHO) criterion for osteoporosis is a BMD score that is 2.5standard deviations below the mean for young adults. BMD measurements in a population of people similar in age and gender roughly follow a Normal distribution.

(a) What percent of healthy young adults have osteoporosis by the WHO criterion?

(b) Women aged 70to79 are, of course, not young adults. The mean BMD in this age group is about 2 on the standard scale for young adults. Suppose that the standard deviation is the same as for young adults. What percent of this older population has osteoporosis?

Airport security The Transportation Security Administration (TSA) is responsible for airport safety. On some flights, TSA officers randomly select passengers for an extra security check before boarding. One such flight had 76 passengers -12 in first class and 64 in coach class. TSA officers selected an SRS of 10 passengers for screening. Let p^be the proportion of first-class passengers in the sample.

(a) Is the 10%condition met in this case? Justify your answer.

(b) Is the Normal condition met in this case? Justify your answer.

Run a mile During World War II, able-bodied male undergraduates at the University of Illinois participated in required physical training. Each student ran a timed mile. Their times followed the Normal distribution with mean 7.11minutes and standard deviation 0.74minute. An SRS of 100of these students has mean time x¯=7.15minutes. A second SRS of size100has mean x¯=6.97minutes. After many SRSs, the values of the sample mean x follow the Normal distribution with mean 7.11 minutes and standard deviation0.074minute.

(a) What is the population? Describe the population distribution. (b) Describe the sampling distribution of x. How is it different from the population distribution?

Making auto parts Agrinding machine in an auto parts plant prepares axles with a target diameter μ=40.125millimeters (mm). The machine has some variability, so the standard deviation of the diameters is σ=0.002mm. The machine operator inspects a random sample of 4axles cach hour for quality control purposes and records the sample mean diameter x¯,how many axles would you need to sample if you wanted the standard deviation of the sampling distribution xto be0.0005mm?justify your answer.
