Random samples of resting heart rates are taken from two groups. Population 1 exercises regularly, and Population 2 does not. The data from these two samples is given below:Population 1: 69, 65, 66, 71, 67, 09, 65Population 2: 78, 76, 69. 77, 70, 60, 69, 68Is there evidence, at an a- 0.035 level of significance, to conclude that there those who exercise regularly have lower resting heart rates? (Assume that the popuation variances are equal andthat the population distributions are normal) Carry out an appropriate hypothesis test, filing in the information requested.A. The value of the test statistic:Note: For the next part, your answer should use interval notation An answer of the form (-00, a) is expressed (-infty, a), an answer of the fom (6, o0) is expressed (b, intty), and an anawer ofthe form (-oo, a) U (b, ) is expressed (-inity, aLb, infty.Hint: For example, note that a rujection region of 'reject Ho if t> t," can be expressed as "reject Ho ift belongs to the interval (ta, 00)".8. The rejection region for the test statistic:C. Run the analysis on Minitab to obtain the p-value:D. Your decision for the hypothesis test:OA Reject Ho.OB. Do Not Reject Ha.OC. Do Not Reject H.D. Reject H1.

3) Two hundred hypertensive patients are assigned to a diet program. Blood pressure is measured on each patient both before the program starts and 3 months after the start of the program. The correct statistical procedure to determine whether or not the mean blood pressure change (after-before) changed significantly different in the patients is: a. Paired t-test b. 2 sample unpaired t-test c. Fisher's exact test (an exact version of the chi-squared test for 2x2 contingency tables) d. None of the above

Researchers were interested in assessing whether stress levels are different at the beginning of the semester compared to finals week. To test this, stress was measured in 5 students at the start of the semester and then again at the end of the semester during finals week.

In 1991, a person was working as an engineer at a paper company when they were laid off in round 2 of several rounds of layoffs by the company. This person sued the company for age discrimination. The engineer claimed that the laid off workers were older than others. The age of randomly selected 10 workers who were laid off and not lay off in round 2 are given below. Test the engineer's claim at 1% level of significance. Note that the data for two samples are in different column.

An ANOVA test is a way to find out if survey or experiment results are significant. In other words, they help you to figure out if you need to reject the null hypothesis or accept the alternate hypothesis. ANOVA is a test between groups to see if there’s a difference between them. State the four assumptions required for one-way ANOVA. How crucial are these assumptions? One-way ANOVA is a procedure for comparing the means of several populations. It is the generalization of what procedure for comparing the means of two populations? In one-way ANOVA, identify the statistic used a. as a measure of variation among the sample means. b. as a measure of variation within the samples. c. to compare the variation among the sample means to the variation within the samples. 4. What is a two-way ANOVA?
A researcher is interested in seeing what effect a particular type of drug has on an intelligence test, depending on the time of day that the pill is administered. The researcher computes a two-way ANOVA and plots the resulting cell means on the graph at right. Assuming that any obvious differences are statistically significant Is there a main effect for type of pill? Is there a main effect for time of day? Is there an interaction? 4. Describe the findings of the study in everyday terms
A different I/O psychologist wants to know if there is a difference in worker evaluations depending if the employee is a male or female. A group of managers were recruited and each rated both 15 men and 15 women employee evaluations on a scale of 0-10. The ratings on the worker evaluations were recorded for each manager. Which statistical test would be best to determine if there is a significant difference between groups? one-sample t-test dependent samples t-test ANOVA
