kodGreya [7K]

Answer:

CI=189.5,194.5

Step-by-step explanation:

From the question we are told that:

Sample size n=40

Mean \=x =192

Standard deviation\sigma=8

Significance Level \alpha=0.05

From table

Critical Value of Z=1.96

Generally the equation for momentum is mathematically given by

 CI =\=x \pm z_(a/2) \frac{\sigma}{\sqrt{n}}

 CI =192 \pm 1.96 \frac{8}{\sqrt{40}}

 CI=192 \pm 2.479

 CI=189.5,194.5
