Assume that the significance level is a = 0.01. Use the given statement allu 1 %3D The test statistic of z =1.10 is obtained when testing the claim that p == 2 of the Normal table

Suppose you had obtained a test statistic of 2.45 (this is incorrect). What would the P-value be? Draw a conclusion based on a = 0.01. Select one: O a. 0.01 < P-value < 0.02, we fail to reject Ho and do not have sufficient evidence to conclude that the mean difference in LDL from switching from an omnivorous to a plant-based diet for 6 weeks is not the same for men and women. O b. 0.005 < P-value < 0.01, we fail to reject Ho and do not have sufficient evidence to conclude that the mean difference in LDL from switching from an omnivorous to a plant-based diet for 6 weeks is not the same for men and women. O c. 0.01 < P-value < 0.02, we reject Ho and have sufficient evidence to conclude that the mean difference in LDL from switching from an omnivorous to a plant-based diet for 6 weeks is not the same for men and women. O d. 0.005 < P-value < 0.02, we reject Ho and have sufficient evidence to conclude that the mean difference in LDL from switching from an omnivorous to a plant-based diet…

The test statistic of z = 1.98 is obtained when testing the claim that p ≠ 0.752. a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. b. Find the P-value. c. Using a significance level of a = 0.10, should we reject Ho or should we fail to reject Ho?

On average is the younger sibling's IQ different from the older sibling's IQ? Ten sibling pairs were given IQ tests. The data are shown below.

The test statistic in a two-tailed test is z= 2.27. Determine the P-value and decide whether, at the 5% significance level, the data provide sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis. E Click here to view a partial table of areas under the standard normal curve. The P-value is (Round to four decimal places as needed.)

Which of the following statistical tools have independent samples? Chi-square Mann-Whitney Wilcoxon Paired t test

QUESTION 12 In the video game Animal Crossing: New Horizons, you can catch and sell both fish and sea creatures. Alison learns that sea creatures sell for a mean of u = 3,345 bells with a standard deviation of o = 3,684 bells ("bells" is the currency in the game). Alison suspects that fish will sell for more money than sea creatures will, so she decides to conduct a hypothesis test at the a = 0.01 level with %3D %3D Họ: µ= 3,345 bells H1: p > 3,345 bells She finds a sample of 64 fish and computes their mean price to be 3,527 bells. a. Determine the standard error to the nearest thousandth. Ox = Work: b. Determine the z-score to the nearest hundredth. Z = Work: c. Identify the image below that best represents the standard normal curve you drew for this problem. A В C
