Question

1)For the following PAIRED OBSERVATIONS, calculate the 95% confidence interval for the population mean mu_d: A = {24.83, 24.84, 24.53}, B = {11.94, 13.07, 9.97}.

choose the correct answer

7.24 < mu_d < 18.91
9.98 < mu_d < 16.17
13.05 < mu_d < 13.09
9.59 < mu_d < 16.56
6.98 < mu_d < 19.17
11.79 < mu_d < 14.36
6.90 < mu_d < 19.25
10.62 < mu_d < 15.53
7.55 < mu_d < 18.59
12.27 < mu_d < 13.88

2)For the following PAIRED OBSERVATIONS, calculate the 90% confidence interval for the population mean mu_d: A = {12.16, 15.65, 12.58, 12.75}, B = {6.02, 8.95, 5.70, 6.22}

6.38 < mu_d < 6.75
5.83 < mu_d < 7.30
5.92 < mu_d < 7.21
5.87 < mu_d < 7.25
5.85 < mu_d < 7.28
6.28 < mu_d < 6.85
6.09 < mu_d < 7.03
6.19 < mu_d < 6.93
6.10 < mu_d < 7.03
5.95 < mu_d < 7.18

3)For the following PAIRED OBSERVATIONS, calculate the 90% confidence interval for the population mean mu_d: A = {19.58, 14.99, 12.30}, B = {7.53, 5.99, 4.08}.

3.41 < mu_d < 16.10
6.34 < mu_d < 13.17
4.02 < mu_d < 15.50
8.78 < mu_d < 10.74
5.11 < mu_d < 14.41
4.24 < mu_d < 15.28
5.59 < mu_d < 13.92
8.53 < mu_d < 10.98
9.17 < mu_d < 10.34
3.69 < mu_d < 15.83

thank you in advance
