Use the given information to find the P-value. Also, use a 0.05 significance level and state the conclusion about the null hypot
Nina [5.8K]

Answer: a. 0.1031; fail to reject the null hypothesis

Step-by-step explanation:

Given: Significance level : \alpha=0.05

The test statistic in a two-tailed test is z = -1.63.

The P-value for two-tailed test : 2P(Z>|z|)=2P(Z>|-1.63|)=0.1031 [By p-value table]

Since, 0.1031 > 0.05

i.e. p-value > \alpha

So, we fail to reject the null hypothesis. [When p<\alpha then we reject null hypothesis  ]

So, the correct option is a. 0.1031; fail to reject the null hypothesis.
