She asked the first groupto meditate every day for 15 minutes for 6 months in addition to their regular counseling sessions. In thesecond group, she continued her regular counseling sessions without any extra treatment.Since the psychologist does not know how to run the analysis, your task is, by using your statistics skills, toinform her whether the mindfulness practice has made a difference in the lives of her clients and in whatsense.To provide her with an answer, I want you to run two different tests: An Independent Samples t-test anda One-Way ANOVA, report their results, and compare the findings of these two analyses.

I am having trouble solving this problem. Can you please provide me with some help? Thank you. I appreciate it. Kentrex, a maker of game consoles, wants to determine whether a proposed new advertising campaign will change gamers' perception of the brand. To conduct the test, Kentrex selected a selected a panel of 6 game players and used an extensive questionnaire to measure brand perception before and after the panel is shown the new campaign through a series of ads. Using the before-and-after brand perception scores in the table below and assuming that the appropriate population conditions are satisfied, construct a hypothesis test of the null hypothesis that there is no difference in average before-and-after scores for the populations. Use a significance level of 5%. player 1 2 3 4 5 6 before 47 52 67 31 62 59 after 57 54 72 37 60 68
The principal of Paul Revere High School bragged that his 2016 graduating class of 1500 students achieved impressive scores on their ACT exams. He announced that an “astounding” 36% of the class got a score of 29 or higher, 54% got a score of 21 to 28, and only 10% less than 21. You want to test whether these ACT results are really that astounding. You visit the ACT website to see that the national results are 34% getting a score over 28, 58% getting 21 to 28, and 8% less than 21. Test whether or not the principal is correct to brag that his proportions were more impressive than the national performance. Use an alpha of 0.05. So I kinda understand the question. I am mostly confused about how to determine the degree of freedom to get the critical value. Like I know the formula is d-C, and C is the number of categories in the word problem, but is there 3? Or am I just totally wrong?
Sean is the star shortstop for his baseball team. He notices that his team typically scores about half as many runs as he has singles, and that his team is about 10% more likely to win a game for each run scored. How likely is it that the team wins if he has 6 singles? How many singles did Sean hit if the team was 70% likely to win?

A college president wanted to know how 10-year-after-graduation salaries for academic majors (English, psychology, math, etc.) compared to salaries for careeroriented majors (business, engineering, computer science, etc.). She matched 84 academic majors at her college with 84 career-oriented majors on the basis of SAT scores and GPA. She found MAcademic = $59,250, MCareer =$61,000, sD = 9,500. Use an alpha of .05 and a two-tailed test to determine if there is a difference in salaries.

In 1940, 2,000 women working in a factory were recruited into a study. Half of the women worked in manufacturing and half in administrative offices. The incidence of bone cancer through 1970 among the 1,000 women working in manufacturing was compared with that of 1,000 women working in administrative offices. Thirty of the women in manufacturing developed bone cancer as compared to 9 of the women in administrative offices. Identify what type of study this is.
This is not a test, its practice.
