Explanation / Answer

6) Rewrite percentages as probabilities:

Percentage= probability*100

6A)36.5% = 36.5/100 = 0.365

6B) 7.1% = 7.1/100= 0.071

7)Two-tailed test Z-critical= +/- 1.79

Rejection region: < -1.79 or > 1.79

7A) Z=-1.80 < -1.79 Reject H0

7B) Z= 0.53 > -1.79 and < 1.79, Fail to reject null hypothesis.
