Chapter 7: Q. 2 (page 454)

Unemployment Each month, the Current Population Survey interviews about 60,000 randomly selected U.S. adults. One of their goals is to estimate the national unemployment rate. In October 2016,4.9% of those interviewed were unemployed.

Short Answer

Expert verified

The population, parameter and statistics respectively are,

  • 60,000adults in the United States were chosen at random.
  • p=sample proportion of unemployed adults in the United States=4.9%=0.049
  • p=the population proportion of unemployed adults in the United States

Step by step solution

01

Given information

We need to find out the population, parameter, sample, and statistics.

02

Explanation

We know that

  • The 4.9percent is based on the 60,000U.S. adults in the sample, therefore 4.9percent indicates the sample proportion of unemployed U.S. adults, implying that 4.9percent is a statistic.
  • The population proportion of unemployed adults in the United States is the corresponding parameter.
  • p=sample proportion of unemployed adults in the United States=4.9%=0.049
  • p=the population proportion of unemployed adults in the United States

In a residential neighborhood, the median value of a house is \(200,000. For which of the

following sample sizes is the sample median most likely to be above \)250,000?

(a) n=10n=10

(b) n=50n=50

(c) n=100n=100

(d) n=1000n=1000

(e) Impossible to determine without more information.

IQ tests The Wechsler Adult Intelligence Scale (WAIS) is a common IQ test for adults. The distribution of WAIS scores for persons over 16 years of age is approximately Normal with mean 100 and standard deviation $15 .

a. What is the probability that a randomly chosen individual has a WAIS score of 105 or greater?

b. Find the mean and standard deviation of the sampling distribution of the average WAIS score x-x炉for an SRS of 60 people. Interpret the standard deviation.

c. What is the probability that the average WAIS score of an SRS of 60 people is 105 or greater?

d. Would your answers to any of parts (a), (b), or (c) be affected if the distribution of WAIS scores in the adult population was distinctly non-Normal? Explain your reasoning.

The number of flaws per square yard in a type of carpet material varies with mean 1.6flaws per square yard and standard deviation flaws per square yard.

a. Without doing any calculations, explain which event is more likely:

  • randomly selecting a1square yard of material and finding 2 or more flaws
  • randomly selecting 50square yards of material and finding an average of 2or more flaws

b. Explain why you cannot use a Normal distribution to calculate the probability of the first event in part (a).

c. Calculate the probability of the second event in part (a).

A researcher initially plans to take an SRS of size 160 from a certain population and calculate the sample mean x-x炉. Later, the researcher decides to increase the sample size so that the standard deviation of the sampling distribution of x-x炉will be half as big as when using a sample size of 160 . What sample size should the researcher use?

a. 40

b. 80

c. 320

d. 640

e. There is not enough information to determine the sample size.

Tall girls According to the National Center for Health Statistics, the distribution of height for 16-year-old females is modeled well by a Normal density curve with mean 渭=64inches and standard deviation 蟽=2.5inches. Assume this claim is true for the three hundred 16-year-old females at a large high school.

a. Make a graph of the population distribution.

b. Imagine one possible SRS of size 20from this population. Sketch a dotplot of the distribution of sample data.
