For Exercises use Table K to determine whether the null hypothesis should be rejected.

ws = 102, n = 28, α = 0.01, one-tailed test

Solutions

Expert Solution

Given that

WS = 102, n = 28 and α = 0.01

 

Find the critical value.

Since n = 18 and α = 0.01 for this two tailed test, the critical value is 92

 

Reject the null hypothesis if the test value is less than the critical value.

 

In this case, since test value, 102 > critical value, 92, the null hypothesis is not rejected.


In this case, since test value, 102 > critical value, 92, the null hypothesis is not rejected.
