Explanation / Answer
Answering the first question as per Chegg policy:
The question clearly states that,
The P value of the statistical decision = 0.1463
Significance level = 0.07
Decision rule: If the P-value of the hypothesis (0.1463) is greater than the significance level (0.07), accept the Null Hypothesis. This is so because the probability of the null hypothesis (14.63% > 7.00%) is so strong (greater than significance level) that it cannot be rejected.
