please help and describe how you got the answer

Assigned ANOVA Problem 1. Darley Ind Latan (1969) examined whether the presence of other people has an inuence on whether a person will help someone in distress. Below is a description of the experimental procedure and summary statistics. 0 The experimenter (a female graduate student) had the subject wait in a room with either 0, 2, or 4 others. Six subjects were randomly assigned to each of those three conditions. 0 She announces that the study will begin shortly and walks into an adjacent room. 0 In a few moments the person in the waiting room hears her fall and complain of ankle pain. a The response is the number of seconds it takes the subject to help the experimenter. # People Present 0 2 4 mean 26.8 33.6 38.2 variance 21.7 20.3 22.7 n 6 6 6 Test whether the mean response time differs for at least one of these conditions. (a) Write the null and alternative hypotheses using statistical notation. (b) Write out the complete AN OVA table and then test at a = ..05 i. First, determine the degrees of freedom from the study design. ii. Then compute the sums of squares using the formulas developed in the Sum of Squares video and reproduced below. iii. Then compute mean squares and the Fratio iv. Use the Matthew Bognar app/webpage to obtain the pvalue from the F distribution. (c) State your inference in the context of the problem. 171: k 333 = 2m is)2 SSW = (n 1) Z 3% 11:1 11:1
