Answer #1

a. 0.25

The z-statistic is computed as follows: -0.053-0.675 X Ho 0.0566 σ/νη - 0.025 22 = 0.675-te-1.64, it is then concluded that the null hypothesis is not Since it is observed that rejected Using the P-value approach: The p-value is p = 0.2497, and since p = 0.2497 > 0.05, it is concluded that the null hypothesis is not rejected.
