Answer 1

solution:

This is the two tailed test .

Test statistic = z=1.95

=

P(z >1.95 ) = 1 - P(z < 1.95 ) = 1-0.9744=0.0256

P-value = 2*0.0256=0.0512

$\alpha$ = 0.05  

P-value < $\alpha$

Reject the null hypothesis

CORRECT OPTION D

b.

This is the two tailed test .

Test statistic = z=-1.63

=

P(z <-1.63) = 0.0516

P-value = 2*0.0516=0.1032

$\alpha$ = 0.05  

P-value > $\alpha$

fail to reject H0

CORRECT OPTION A
