A 7,000-seat theater is interested in determining whether there is a difference in attendance between shows on Tuesday evening and those on Wednesday evening. Two independent samples of 17 weeks are collected for Tuesday and Wednesday. The mean attendance on Tuesday evening is calculated as 5,410, while the mean attendance on Wednesday evening is calculated as 5,870. The known population standard deviation for attendance on Tuesday evening is 570 and the known population standard deviation for attendance on Wednesday evening is 440. Which of the following is the value of the appropriate test statistic? Multiple Choice tdf = 2.6340 z = -2.6340 taf = -2.6340 z = 2.6340
