may need to use the appropriate appendix table or technology to answer this question. der the following hypothesis test: H₁: P = 0.5 H₂: P = 0.5 mple of 600 provided a sample proportion of 0.59. Determine the standard error of the proportion. (Round your answer to five decimal places.) Compute the value of the test statistic. (Round your answer to two decimal places.) Determine the p-value, and using a = 0.05, test the hypotheses. Find the p-value. (Round your answer to four decimal places.) p-value = State your conclusion. O Reject H. There is insufficient evidence to conclude p differs from 0.5. O Do not reject H. There is sufficient evidence to conclude p differs from 0.5. O Do not reject H. There is insufficient evidence to conclude p differs from 0.5. O Reject H. There is sufficient evidence to conclude p differs from 0.5.

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 want to obtain a sample to estimate a population mean. Based on previous evidence, you believe the population standard deviation is approximately o = 74.4. You would like to be 90% confident that your estimate is within 4 of the true population mean. How large of a sample size is required? n=

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.

We want to conduct a hypothesis test of the claim that for middle-aged adults the population mean of their cholesterol levels is less than 191.7 mg dL mg dL mg a random sample of such levels. The sample has a mean of 190.7 dL -0 O It is unclear which test statistic to use. For each of the following sampling scenarios, choose an appropriate test statistic for our hypothesis test on the population mean. Then calculate that statistic. Round your answers to two decimal places. (a) The sample has size 110, and it is from a non-normally distributed population with a known standard deviation of 19.1. Oz = 0t= (b) The sample has size 14, and it is from a population with a distribution about which we know very little. 2-0 Oz= 01-0 O It is unclear which test statistic to use. and a standard deviation of 18 Explanation Check .
