Tina catches a 14-pound bass. She does not know the population mean or standard deviation. So she takes a sample of five friends and they say the last bass they caught was 9, 12, 13, 10, and 10 pounds. Find the t and calculate a 95% (α = .05) confidence interval.
A college administrator claims that the proportion of students that are nursing majors is greater than 40%. To test this claim, a group of 400 students are randomly selected and its determined that 190 are nursing majors. The following is the setup for this hypothesis test: Ho : p=0.40 Ha: p > 0.40 Find the test statistic for this hypothesis test for a proportion. Round your answer to 2 decimal places. Provide your answer below: TestStatistic

You may need to use the appropriate technology to answer this question. Use the sample data below to test the hypotheses Ho:P1 = P2 = P3 H3i not all population proportions are equal where p, is the population proportion of Yes responses for population i. Populations Response 1 3 Yes 140 150 106 No 90 150 114 Find the value of the test statistic. (Round your answer to three decimal places.) Find the p-value. (Round your answer to four decimal places.) p-value Using a 0.05 level of significance, state your conclusion. O Do not reject Ho. We conclude that not all population proportions are equal. Do not reject Ho: We cannot conclude that not all population proportions are equal. Reject Ho. We conclude that not all population proportions are equal. O Reject Ho: We cannot conclude that not all population proportions are equal.
