Random samples of resting heart rates are taken from two groups. Group 1 exercises regularly, and Group 2 does not. The data from these two samplesis given below:Group 1: 62, 71, 62, 68, 69, 69, 72Group 2: 78, 74, 73, 76, 76, 71, 70, 76Is there evidence, at an a = 0.07 level of significance, to conclude that there those who exercise regularly have lower resting heart rates? Carry out anappropriate hypothesis test, filling in the information requested.A. The value of the standardized test statistic (round summary statistics to 3 decimal places and test statistic to three decimal places):Note: For the next part, your answer should use interval notation. An answer of the form (-∞, a) is expressed (-infty, a), an answer of the form (b, ∞)is expressed (b, infty), and an answer of the form (-∞, a) U (b, ∞) is expressed (-infty, a)U(b, infty).B. The rejection region for the standardized test statistic:C. The p-value isD. Your decision for the hypothesis test:A. Reject H₁.B. Do Not Reject H₁.C. Do Not Reject Ho.D. Reject Ho.

Researchers investigate how the presence of cell phones influence the quality of human interaction. Subjects are randomly selected from a population and divided into an experimental group that is asked to leave their phones in the front of the room and a control group that are not asked to leave their cell phones at the front of the room. Subjects are left alone for 10 minutes and then asked to take a survey designed to measure quality of interactions they had with others in the experiment. What statistical test is appropriate?
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
Three groups of physical therapy patients were subjected to different treatment regimens. At the end of a specificed time period each was given a test to measure effectiveness. The following data was obatined.

An investigation is performed to evaluate two new experimental treatments for allergies. 18 subjects who suffer from allergies are enrolled in the study and randomly assigned to one of three treatments: Control Group, Experimental Treatment 1, or Experimental Treatment 2. Each subject is instructed to take the assigned treatment, and symptoms of allergies are recorded on a scale of 1 to 20, with higher scores indicating worse symptoms. The data is summarized in the table below: SBP Std. Deviation Group Mean Control Treatment 6. 16.17 2.483 Experimental Treatment 1 6. 11.33 1.966 Experimental Treatment 6. 3.83 1.472 Total 18 10.44 5.554 Use this data to complete an ANOVA table to test for a significant difference in the means of each of the groups. Round all answers to the third decimal point.
