A sales organization conducted a study to explore sales strategies, processes, and support systems within businesses. Organizations were categorized by sales performance level (top performers vs. middle performers vs. bottom performers) and extent to which the organization invests in customer satisfaction. Results were organized into the accompanying contingency table. At the 0.01 level of significance, is there evidence of a significant relationship between sales performance level and level of investment in customer satisfaction? What are the null and alternative hypotheses to test? Ho: relationship exists between relationship exists between H₁: Calculate the test statistic. X²STAT = (Round to two decimal places as needed.) The p-value for XSTAT is. (Round to three decimal places as needed.) and and (...)

6. Which of the following statements are true? Report true statement(s), if any. No reasons necessary. You don't need to write out the statement(s) - just write (a), (b) or whatever. (a) A P-value conveys much information about the strength of evidence against the null hypothesis and allows an individual decision maker to draw a conclusion at any specified significance level. (b) If the P-value is greater than the significance level a, we reject the null hypothesis at Jevel a.
Part C, D and E please, Thank You! D) What is the null hypothesis? E) Reject the null hypothesis because the P-value is greater than the significant level, a Reject the null hypthosesis because the P-value is less than or equal to the significant level, a Fail to reject the null hypothesis because the P-value is greater than or equal to the significant level, a Fail to reject the null hypothesis because the P-Value is greater than the significant level, a

You receive a brochure from a large university. The brochure indicates that the mean class size for full-time faculty is fewer than 31 students. You want to test this claim, You randomly select 18 classes taught by full-time faculty and determine the class size of each. The results are shown in the table below, At a = 0.01. can vou support the university's claim? Complete parts (a) through (d) below. Assume the population is normally distributed. 32 26 27 30 31 37 23 28 320 29 27 37 32 31 25 31 29 22 (a) Write the claim mathematically and identify Ho and Ha. Which of the following correctly states Ho and Ha? O C. Ho: H=31 O A. Ho: H> 31 Hai H531 O B. Ho: H231 Ha:H31 (b) Use technology to find the P-value. P= (Round to three decimal places as needed.) (c) Decide whether to reject or fail to reject the null hypothesis. Which of the following is correct? O A. Fail to reject Ho because the P-value is less than the significance level. O B. Reject H because the P-value is less than the…
A researcher believes that more than half of college students average less than 6 hours of sleep per night during the week. Suppose she collected data to test her belief and found a p-value < 0.0001. Fill in the information for her hypothesis test below. Type of test: a. Left-tail b. Right-tail c. Two-tail
(b)Based on your answer to part (a), which statement below is true? Since the p-value is less than (or equal to) the level of significance, the null hypothesis is rejected. Since the p-value is less than (or equal to) the level of significance, the null hypothesis is not rejected. Since the p-value is greater than the level of significance, the null hypothesis is rejected. Since the p-value is greater than the level of significance, the null hypothesis is not rejected.
These are the answer selections for the drop-down boxes. The hypothesis test will be (two tailed, left-tailed, right-tailed) Reject the (alternative, null) hypothesis that the proportion of people who read books in print is (less than, equal to, greater than, not equal to) 0.25 in which case there is evidence (in support of, to reject) Do not reject the (null, alternative) hypothesis, in which case there is not enough evidence to (reject, support)the claim that the proportion of people who read books in print is not equal to 0.25.
The Pavalue for a hypothesis test is shown. Use the P-value to decide whether to reject Ho when the level of significance is (a) a = 0.01, (b) a = 0.05. and (c)g=0 10 P=0.0816 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? O A. Fail to reject Ho because the P-value, 0.0816, is less than a = 0.01. O B. Fail to reject H, because the P-value, 0.0816, is greater than a= 0.01. OC. Reject H, because the P-value, 0.0816, is less than a=0.01. O D. Reject Ho because the P-value, 0.0816, is greater thana= 0.01. (b) Do you reject or fail to reject H, at the 0.05 level of significance? O A. Reject Ho because the P-value, 0.0816, is less than a =0.05. O B. Fail to reject H, because the P-value, 0.0816, is greater than a= 0.05. OC. Reject H, because the P-value, 0.0816, is greater than oa 0.05. O D. Fail to reject Ho because the P-value, 0.0816, is less than a = 0,05. (c) Do you reject or fail to reject Ho at the 0.10 level of significance? O A. Reject Ho because the…
In this case, p-value is greater. So null hypothesis should not be rejected, correct?
