please show all the work so I know how to do it

3) The data that follow are based on a study by Qa_r_|_e_y and j._a_ta_n_ (1969). The authors were interested in whether the presence of other people has an inuence on whether a person will help someone in distress. In this classic study, the experimenter (a female graduate student) had the subject wait in a room with 0, 2, or 4 other people. The experimenter announces that the study will begin shortly and walks into an adjacent room. In a few moments the person(s) in the waiting room hear her fall and complain of ankle pain. The dependent measure is the number of seconds it takes the subject to help the experimenter. The data are given below: 0 People Present 2 People Present 4 People Present 25 30 32 30 33 39 20 29 35 32 40 41 36 44 Sample Mean 26.75 33.6 38.2 Sample SD 5.38 4.51 4.76 a. Calculate the grand mean, x. b. Calculate the sum of squares between samples, SSE. c. Calculate the sum of squares within samples, SSW. d. Fill in an ANOVA table like the following: Source Sum of Squares df Mean Square F Statistic Between Within Total e. At the 0.01 significance level, conduct a full hypothesis test regarding whether the number of people present seems to influence the time it takes for someone to help someone else in distress. Show all 6 steps. Note that you already calculated the test statistic in parts a. through d. above. You do not need to show additional work for Step 3 of the hypothesis test
