A test was conducted of two overnight mail delivery services. Two samples of identical deliveries were set up so that both delivery services were notified of the need for a delivery at the same time. The hours required to make each delivery follow. Do the data shown suggest a difference in the delivery times for the two services? Use a .05 le of significance for the test. Use Table 1 of Appendix B. Click on the datafile logo to reference the data.

hi, if you could help me with this problem that would be very helpful. thank you.
In a study, a random sample of 20 adults rated the effectiveness of advertisements. Each adult rated an advertisement that lasted 30 or 60 seconds. The block design in the accompanying table shows these ratings (on a scale of 1 to 5, with 5 being extremely effective). Use a = 0.05 and a technology tool and the given block design to perform a two-way ANOVA test. Click the icon to view the block design and ratings. Determine the null and alternative hypotheses for the main effects. Select all that apply. O A. Ho: The length of the ad has no effect on the rating. B. Ho: The rating has no effect on the advertising medium. Ha: The rating has an effect on the advertising medium. Ha: The length of the ad has an effect on the rating. O c. Ho: The advertising medium has no effect on the rating. D. Ho: : The advertising medium has no effect on the length of the ad. Ha: The advertising medium has an effect on the rating. : The advertising medium has an effect on the length of the ad. Ha: length…

Rhino viruses typically cause common colds. In a test of the effectiveness of echinacea, 42 of the 48 subjects treated with echinacea developed rhinovirus infections. In a placebo group, 95 of the 111 subjects developed rhinovirus infections. Use a 0.05 significance level to test the claim that echinacea has an effect on rhinovirus infections. Complete parts (a) through (c) below. Identify the test statistic. z = 0.32 (Round to two decimal places as needed.) Identify the P-value. P-value = 0.748 (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? The P-value is greater than the significance level of a = 0.05, so fail to reject the null hypothesis. There is not sufficient evidence to support the claim that echinacea treatment has an effect. b. Test the claim by constructing an appropriate confidence interval. The 95% confidence interval is< (P1- P2) < (Round to three decimal places as needed.) clinical trial Get more help- Clear all esc %23 3…
