Answer 1

Solution

1) T-Value (Left-tailed): - 2.897

2)

4)

The Chi-Square critical value for a right-tailed test, for a significance level of a = 0.05 is: Xi = 26.296

The Chi-Squared statistic is computed as follows: (n-1)s? (15 – 1).3 3.6 = 11.667

5)

The Chi-Square critical values for a two-tailed test, for a significance level of a = 0.01 are: x = 9.26 and x = 44.181
