Explanation / Answer

Since given test is right tailed test so

P- value = P( Z>1.87)

= 1- P (Z<1.87)

= 1 - .9693

=0.0307

Since P( Z<1.87)= .9693 from the z table.

So P value = 0.0307

Rejection rule :

If P value is less than level of significance then we reject the null hypothesis.

Here p value is less than 0.06

Hence we reject the null hypothesis .
