Do people walk faster in an airport when they are departing (getting on a plane) or after they have arrived (getting off a plane)? An interested passenger watched a random sample of people departing and a random sample of people arriving and measured the walking speed (in feet per minute) of each. A hypothesis test is to be performed to determine if the mean walking speed is different between departing and arriving passengers at an airport. Suppose the p-value is 0.14. What is an appropriate conclusion? Choose the correct answer below. O A. There is sufficient evidence at the 5% significance level to indicate that the mean walking speeds for arriving and departing passengers are the same. B. There is not sufficient evidence at the 5% significance level to indicate that the mean walking speeds for arriving and departing passengers are different. C. There is not sufficient evidence at the 5% significance level to indicate that the mean walking speeds for arriving and departing passengers…
From long-term observation, it is known that the waiting-time for non-ambulance adult arrivals in a hospital's A&E has a mean of 120 minutes and a standard deviation of 50 minutes. On a given day, there are 200 such arrivals. Management want to set a daily target for the mean waiting time that will be met 95% of the time with 200 arrivals. What mean should they specify? O 202.24 minutes O 124.53 minutes O 126.93 minutes O 125.82 minutes
The heart rates before and after running a race (in beats per minute) of a sample of four athletes are shown in the following table: Athlete Heart rate before Heart rate after 120 129 134 123 50 52 3 56 4 53 The aim of the experiment was to determine whether the population mean heart rate after a race is more than 70 beats per minute greater than before the race. 1.4 Use the appropriate hypotheses test to determine whether the population mean heart rate after a race is more than 70 beats per minute greater than before the race. Use a = 0.05 and also find the approximate p-value. Also mention any assumptions made. Using your answer in 1.4), comment on whether you are subject to a Type I or a Type II error. Describe this error in the context of this problem. Estimate the difference in the mean heart rate by calculating a 90% confidence intervai for the data. Use this result to determine whether the population mean heart rate after a race is more than 70 beats per minute greater than…
(a) The population 3, 4, 9, 14, and 20 has a mean of 10 and a standard deviation of 6.356. The z-scores for each of the five data values are z3 ≈ −1.101, z4 ≈ −0.944, z9 ≈ −0.157, z14 ≈ 0.629, and z20 ≈ 1.573. Find the mean and the standard deviation of these z-scores. mean standard deviation (b) The population 2, 6, 12, 17, 22, and 25 has a mean of 14 and a standard deviation of 8.226. The z-scores for each of the six data values are z2 ≈ −1.459, z6 ≈ −0.973, z12 ≈ −0.243, z17 ≈ 0.365, z22 ≈ 0.973, and z25 ≈ 1.337. Find the mean and the standard deviation of these z-scores. mean standard deviation (c) Use the results of part (a) and part (b) to make a conjecture about the mean and standard deviation of the z-scores for any set of data. The mean of the z-scores is always 1, and their standard deviation is 0. The mean of the z-scores is always 1 more than the standard deviation. The mean and standard deviation of z-scores are never the same.…

b) Rachel received the following scores on the midterm and final examinations in his introductory psychology course. The mean and the standard deviation for each test are given below. Assume that the normal distribution provides a good model for the frequency distribution. Section 8. 40 90 |Midterm 50 Final 100 12 i. What percentage of students scored better than Rachel on the midterm? The department has decided that all marks from introductory psychology courses should be reported based on a standardized distribution with a mean of 100 and standard deviation of 15. What would be Rachel's final examination scores based on ii. this new distribution?

Mark performed a two-sample z-test for proportions to test the hypothesis that there was no difference in the proportion who support increasing student fees between male and female students at a particular university. Mark obtained a z-statistic of 0. Based on this information, which of the following is always true. The sample proportions for male and females will be the same as the hypothesized proportions for male and female students at this university. The sample proportions for both male and female students at this university will be 0. All male and female students in the sample will feel the same way about supporting the increase in student fees. The sample proportions will be the same for both male and female students at this university. Test whether p1>p2 The sample data are x1=116,n1=258,x2=135,n2=311. Conduct a test at the α=0.10 level of significance. Determine the correct null and alternative hypothesis below. Determine the test statistic. Find the P-value: What is…
