Chapter 7: Q. R7.1 (page 438)

Bad eggs Selling eggs that are contaminated with salmonella can cause food poisoning in consumers. A large egg producer randomly selects 200 eggs from all the eggs shipped in one day. The laboratory reports that 9 of these eggs had salmonella contamination. Identify the population, the parameter, the sample, and the statistic.

Short Answer

Expert verified

The population are eggs in a days , the parameter is 0.001, A descriptive measure for a sample is the statistic., and the statistic is 0.045.

Step by step solution

01

Given Information

A few rotten eggs Consumers may get food poisoning if they buy eggs that are tainted with salmonella. A huge egg producer chooses 200 eggs at random from all the eggs shipped in a single day. Salmonella was found in 9 of the eggs, according to the laboratory.

02

Simplification

Individuals who are being examined make up the population.

All of the eggs were laid in one day.

The sample is the portion of the population from whom data was gathered.

200 eggs were randomly selected as a sample.

The parameter is a population descriptive measure.

The proportion of salmonella-infected eggs shipped that day is the parameter.

P=0.1%=0.001

A descriptive measure for a sample is the statistic.

The proportion of eggs in the sample that contain salmonella is a statistic.

p^=9200=0.045

Tall girls? To see if the claim made in Exercise 12is true at their high school, an Ap Statistics class chooses an SRS of twenty 16-year-old females at the school and measures their heights. In their sample, the mean height is 64.7inches. Does this provide convincing evidence that 16-year-old females at this school are taller than 64inches, on average?

a. What is the evidence that the average height of all 16-year-old females at this school is greater than 64inches, on average?

b. Provide two explanations for the evidence described in part (a).

We used technology to simulate choosing 250SRSs of size n=20from a population of three hundred 16-year-old females whose heights follow a Normal distribution with mean localid="1654113150676" 渭=64inches and standard deviation 渭=2.5inches. The dotplot shows x=the sample mean height for each of the 250simulated samples.

c. There is one dot on the graph at 62.5. Explain what this value represents.

d. Would it be surprising to get a sample mean of x=64.7or larger in an SRS of size 20when 渭=64inches and 蟽=2.5inches? Justify your answer.

e. Based on your previous answers, is there convincing evidence that the average height of all 16-year-old females at this school is greater than 64inches? Explain your reasoning.

A large company is interested in improving the efficiency of its customer service and decides to examine the length of the business phone calls made to clients by its sales staff. Here is a cumulative relative frequency graph from data collected over the past year. According to the graph, the shortest 80% of calls will take how long to complete?

a. Less than 10 minutes

b. At least 10 minutes

c. Exactly 10 minutes

d. At least 5.5 minutes

e. Less than 5.5 minutes

When people order books from a popular online source, they are shipped in boxes.

Suppose that the mean weight of the boxes is 1.5 pounds with a standard deviation of 0.3 pound, the mean weight of the packing material is 0.5pound with a standard deviation of 0.1 pound, and the mean weight of the books shipped is 12 pounds with a standard deviation of 3 pounds. Assuming that the weights are independent, what is the standard deviation of the total weight of the boxes that are shipped from this source?

a. 1.84

b. 2.60

c. 3.02

d. 3.40

e. 9.10

Increasing the sample size of an opinion poll will reduce the

a. bias of the estimates made from the data collected in the poll.

b. variability of the estimates made from the data collected in the poll.

c. effect of nonresponse on the poll.

d. variability of opinions in the sample.

e. variability of opinions in the population.
