Among 888 male students, 268 had blue eyes. Among 1135 female students,441 had blue eyes. Use a 0.01 significance level to test the claim that the proportions of blue eyes are the same for males and females. Complete parts (a) through(c) below. Consider the first sample to be the sample of males and the second sample to be the sample of females.a. Test the claim using a hypothesis test.What are the null and alternative hypotheses for the hypothesis test?O A. Hg: P1 = P2H1: P1 > P2O B. Ho: P1 S P2H1: P1 + P2O C. Ho: P1 = P2H1: P1 + P2O D.

A political candidate has asked you to conduct a poll to determine what percentage of people support her. If the candidate only wants a 2% margin of error at a 99% confidence level, what size of sample is needed? Hint: Textbook 2 Video 2 [+]
There are many products that on their label, establish a content of the packaging. Select a brand of cleaning detergent (for example ACE or Tide). In their label, they establish a weight of the amount of detergent in each box. Choose a sample of 8 boxes from the selected company and weight the 8 samples on a scale. Collect this information and build a hypothesis test, a confidence interval, a P – value and size of sample (n) by comparing the average weight of the samples with the one on the box label. It determines, through the hypothesis test, if there is any difference in the average weight of the sample boxes with the one that appears in the box. Use an alpha for this 0.01 test. What is your conclusion?

You are trying to study the level of personal net worth of a low income populaon. In parcular you are interested in find the confidence interval of the mean level of net worth (net worth can be posive or negave and is measured in thousands of dollars). You do not know the distribuon of the level of net worth of the populaon. For your study, you collected a sample from 100 persons asking them their level of net worth. The results were such that the sample meanXˉ = 3 and the sample variance Sn2 = 100 (Assume you choose the persons randomly, they report their true net worth, and the populaon is sufficiently large.) From this data, find the 90% confidence interval of the mean level of net worth.(Do not use t distribuon)
Setting the confidence level at 90\% instead of 95% decreases the sample size decreases the width of the confidence interval increases the width of the confidence interval increases the sample size

help thank you!! A new method of HIV testing has been proposed based on a new quick detection procedure where saliva is examined. Suppose that the new method tests 176 HIV positive persons and falsely categorizes (i.e., return negative results) 25 of them. Assuming the current best standard of practice for saliva based quick detection HIV tests has a false negative rate of only 10%, determine if the accuracy of the two tests are significantly different at 95% confidence level. Assume that we can use a z-test. Let ?=False negative rate of new test What is the mean and standard deviation of the normal approximation for p-hat under Null hypothesis? answer choices
