Step 1

 It is provided that,

The critical z values  are -1.96 and +1.96 respectively.

z- score is -1.90.

Step 2

Decision based on the critical value method for the two-tailed suggests that

Reject the null hypothesis (H). if | = |2l .

Reject the null hypothesis (H). if | = |2l .

Step 3

The critical value is ±1.96 an...
