Psychology experiments sometimes involve testing the ability of rats to navigate a maze. One researcher needs a maze that will take rats, on average, less than a minute to solve. The data below (image provided) gives the completion times for this maze for 20 randomly sampled rats. Will the maze fulfill the researcher’s time requirement? Use a significance level of ? = 0.05. What are the hypotheses. What are the test statistic and p-value. What is the full conclusion for this test in the context of the problem.
You may need to use the appropriate appendix table or technology to answer this question. A survey asked senior executives at large corporations their opinions about the economic outlook for the future. One question was, "Do you think that there will be an increase in the number of full-time employees at your company over the next 12 months?" In the current survey, 228 of 400 executives answered Yes, while in a previous year survey, 176 of 400 executives had answered Yes. Provide a 95% confidence interval estimate for the difference between the proportions at the two points in time. (Use current year previous year. Round your answer to four decimal places.) to What is your interpretation of the interval estimate? The 95% confidence interval ---Select--- ✓zero. This suggests that the proportion of executives who are predicting an increase in full- time jobs for the current year is ---Select--- ✓ than the proportion of executives who were predicting an increase in full-time jobs for the…

Question: Part B. Construct a 95% confidence interval of the mean pulse rate for adult males. __bpm <u<__bpm Multiple Choice: Compare the results. A. The confidence intervals do not overlap, so it appears that adult females have a significantly higher mean pulse rate than adult males. B. The confidence intervals overlap, so it appears that adult males have a significantly higher mean pulse rate than adult females. C. The confidence intervals do not overlap, so it appears that there is no significant difference in mean pulse rates between adult females and adult males. D. The confidence intervals overlap, so it appears that there is no significant difference in mean pulse rates between adult females and adult males.
