Question 11 > 0/1 pt 5 3 8 Details Two samples are taken with the following numbers of successes and sample sizes r1 = 23 r2 = 34 n1 = 82 n2 = 76 Find a 91% confidence interval, round answers to the nearest thousandth. 0/1 pt 5 3 0 Details Test the claim that the proportion of men who own cats is smaller than the proportion of women who own cats at the .05 significance level. The null and alternative hypothesis would be: Ho : UM = UF HO :PM = PF Ho : MM = MF H1 : UM PF H1 : MM > MF Ho : UM = UF HO : PM = PF Ho : PM = PF H1 : UM # MF H1:PM IE; on pt '0 3 G) Details You wish to test the following claim (Ha) at a signicance level ofa : 0.001. You obtain 37 successes in a sample of size 511 : 220 from the rst population. You obtain 163 successes in a sample of size 5-12 : 682 from the second population. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = l ' What is the pValue for this sample? (Report answer accurate to four decimal places.) p-value = l l The pvalue is... 0 less than (or equal to) o: O greater than or This test statistic leads to a decision to... O reject the null O accept the null O fail to reject the null . Question 8 0/1 pt 9 3 0 Details You are testing the claim that the proportion of men who own cats is significantly different than the proportion of women who own cats. You sample 130 men, and 75% own cats. You sample 190 women, and 65% own cats. Find the pooled value of p, as a decimal, rounded to two decimal places.Question 7 > 0/1 pt 3 0 Details A student was asked to find a 90% confidence interval for the proportion of students who take notes using data from a random sample of size n = 84. Which of the following is a correct interpretation of the interval 0.11 E4 on pt '0 3 G) Details Out of 400 people sampled, 72 had kids. Based on this, construct a 99% condence interval for the true population proportion of people with kids. Give your answers as decimals, to three places | |{p{ za \\ .- Question 5 0/1 pt 5 3 8 Details For a confidence level of 98%, find the critical valueQuestion 4 0/1 pt 5 3 0 Details You want to obtain a sample to estimate a population proportion. Based on previous evidence, you believe the population proportion is approximately p* = 44% . You would like to be 90% confident that your esimate is within 2.5% of the true population proportion. How large of a sample size is required? D= Do not round mid-calculation. However, use a critical value accurate to three decimal places.. Question 3 A V 0/1 pt 5 3 - Details If n=120 and p (p-hat) =0.22, find the margin of error at a 99% confidence level Give your answer to three decimalsQuestion 2 > 0/1 pt 9 3 0 Details Giving a test to a group of students, the grades and gender are summarized below A B C Total Male 16 11 19 46 Female 5 12 10 27 Non-binary 14 4 2 20 Total 35 27 31 93 Let 7 represent the percentage of all non-binary students who would receive a grade of C on this test. Use a 90% confidence interval to estimate p to three decimal places. Enter your answer as a tri-linear inequality using decimals (not percents).

B 0/1 pt '0 3 G) Details We wish to estimate what percent of adult residents in a certain county are parents. Out of 400 adult residents sampled, 244 had kids.
