A recent study focused on the number of times men and women send a Twitter message in a day. The information is summarized here. Sample Size Sample Mean Population Standard Deviation Men 25 23 5 Women 30 28 10 Assume that women are population 1 and men are population 2. At the 0.01 significance level, is there a difference in the mean number of times men and women send a Twitter message in a day? Based on the p-value, what is your conclusion? Multiple Choice Reject the null hypothesis and conclude the means are different. Reject the null hypothesis and conclude the means are the same. Fail to reject the null hypothesis.
