Reporting cheating What proportion of students are willing to report cheating by other students? A student project put this question to an SRS of 172 undergraduates at a large university: 鈥淵ou witness two students cheating on a quiz. Do you go to the professor?鈥� Only 19 answered 鈥淵es.鈥�3

Short Answer

Expert verified

The sample proportion isp^=11.05%.

Step by step solution

01

Given Information

n=Sample size=172

x=Number of successes=19

02

Explanation

The population proportion pis estimated by the sample proportion p^.

The sample proportion is the number of successes divided by the sample size.

p^=xn=19172鈮�0.1105=11.05%.

61. Willows in Yellowstone Writers in some fields summarize data by giving x炉and its standard error rather than x炉and sx. Biologists studying willow trees in Yellowstone National Park reported their results in a table with columns labeled x炉+SE. The table entry for the heights of willow trees (in centimeters) in one region of the park was 61.55卤19.03.The researchers measured a total of23 trees.
(a) Find the sample standard deviation sx for these measurements. Show your work.
(b) Explain why the given interval is not a confidence interval for the mean height of willow trees in this region of the park.

6. Auto emissions Oxides of nitrogen (called NOXfor short) emitted by cars and trucks are important contributors to air pollution. The amount of NOX
emitted by a particular model varies from vehicle to vehicle. For one light-truck model, NOXemissions vary with mean 渭that is unknown and standard deviation 蟽=0.4gram per mile. You test an SRSof 50of these trucks. The sample mean NOXlevel xestimates the unknown 渭. You will get different values of xif you repeat your sampling.

(a) Describe the shape, center, and spread of the sampling distribution of x.
(b) Sketch the sampling distribution of x. Mark its mean and the values one, two, and three standard deviations on either side of the mean.
(c) According to the 68鈥�95鈥�99.7rule, about 95%of all values of xlie within a distance mof the mean of the sampling distribution. What is m? Shade the region on the axis of your sketch that is within m of the mean.
(d) Whenever x炉falls in the region you shaded, the unknown population mean 渭lies in the confidence interval x卤m. For what percent of all possible samples does the interval capture 渭?

Researchers were interested in comparing two methods for estimating tire wear. The first method used the amount of weight lost by a tire. The second method used the amount of wear in the grooves of the tire. A random sample of 16tires was obtained. Both methods were used to estimate the total distance traveled by each tire. The table below provides the two estimates (in thousands of miles) for each tire.

(a) Construct and interpret a 95%confidence interval for the mean difference 渭in the estimates from these two methods in the population of tires.

(b) Does your interval in part (a) give convincing evidence of a difference in the two methods of estimating tire wear? Justify your answer.

Bone loss by nursing mothers.: Breastfeeding mothers secrete calcium into their milk. Some of the calcium may come from their bones, so mothers may lose bone minerals. Researchers measured the per cent change in bone mineral content (BMC) of the spines of 47randomly selected mothers during three months of breastfeeding. The mean change in BMC was 3.587%and the standard deviation was 2.506%.

(a) Construct and interpret a 99% confidence interval to estimate the mean per cent change in BMC in the population.

(b) Based on your interval from (a), do these data give good evidence that on average nursing mothers lose bone minerals? Explain
