Suppose that a random sample of 11 adult US males has a mean height is 69 inches with a standard deviation of 2.9 inches. If we assume that the height of adult males in the US are normally distributed, find a 90% confidence interval for the mean height of all US meals. Give the lower limb and upper limit of the 90% confidence interval. Carrier intermediate computations to at least three decimal places. Andrew answers to one decimal point.
A pharmaceutical company claims that its new drug reduces systolic blood pressure. The systolic blood pressure (in millimeters of mercury) for nine patients before taking the new drug and 22 hours after taking the drug are shown in the table below. Using this data, find the 90%90% confidence interval for the true difference in blood pressure for each patient after taking the new drug. Assume that the blood pressures are normally distributed for the population of patients both before and after taking the new drug.

Suppose that the population of lengths of all fully grown male killer whales is approximately normally distributed. A recent article published in the Zoology Now journal claims that the mean of this population is 6.99 m. You want to test the claim made in the article, so you select a random sample of 10 fully grown male killer whales and record the length of each. Follow the steps below to construct a 90% confidence interval for the population mean of all lengths of fully grown male killer whales. Then state whether the confidence interval you construct contradicts the article's claim. (If necessary, consult a list of formulas.) (a) Click on "Take Sample" to see the results for your random sample. (b) Take Sample Point estimate: 0 Sample standard deviation: 0 Critical value: 0 Compute Enter the values of the sample size, the point estimate of the mean, the sample standard deviation, and the critical value you need for your 90% confidence interval. (Choose the correct critical value…
The campus paper reported that the average hours of sleep for students at a neighboring university is 6.5 hours. This has made you curious about the amount of sleep students at your university get. You randomly selected four students on your campus and their amounts of sleep are 5, 3, 6 and 2 and has a sample mean of 4.0 hours. What is the 95% confidence interval for μ? I ended up with an answer of 95% CI [-1,5] Is this correct? do I need to do a hypothesis t-test? It's only asking for the CI so that's what I did.
A 95% two-sided confidence interval for μ which has been calculated using R turns out to be (0, 1). A 90% two-sided confidence interval based on the same data will contain the value 0.9 (True, cannot tell, or False)
A random sample of size 30 from a normal population yields x̅ = 69 and s = 4. The lower bound of a 95 percent confidence interval is (Round off upto 2 decimal places).

We would like to compute a 95% confidence interval for the difference of proportions of men and women who are frequent binge drinkers. Of 534 males, 26% admitted to frequent binge drinking as opposed to 20.6% of 847 women. The 95% confidence interval for the difference of proportions (proportion of males - proportion of females) is (0.0179, 0.1001). Based on this confidence interval, can we conclude that men are more likely to frequently binge drink than women? (4)
A random sample of ni = 270 people who live in a city were selected and 99 identified as a "dog person." A random sample of n2 = 108 people who live in a rural area were selected and 51 identified as a "dog person." Find the %3D 98% confidence interval for the difference in the proportion of people that live in a city who identify as a "dog person" and the proportion of people that live in a rural area who identify as a "dog person." Round answers to to 4 decimal places. < pi – P2 < -
According to a survey the percent of high school graduates is 69%. One city wanted to know if the proportion of high school graduates is different from the known national proportion. The city samples 150 citizens to know if the proportion of high school graduates and 98 are graduates. (10 points) State the null and alternative hypotheses. What is the value for the t-test for the proportion? For α = .05 (two-tailed) what is the appropriate p value?
