a)

Z score 1.86

Significance level 0.05

Two tailed

The P-Value is 0.062886

The result is not significant at p < 0.05

So, we need to reject the null hypothesis

b)i.

z score = 1.86

significance 0.05

The P-Value is 0.062886

So, we need to reject the null hypothesis

b)ii.

z score = 1.86

significance 0.08

The P-Value is 0.062886

so, we need to accept the null hypothesis
