Answer:

b. The p-value is greater than 0.05.

Step-by-step explanation:

When we are testing a hypothesis, we have to look at the pvalue.

If the pvalue is less than the significance level, the null hypothesis is not plausible. Otherwise, if the pvalue is more than the significance level, the null hypothesis is plausible.

In this question:

95% means that the significance level is of 1 - 0.95 = 0.05.

Null hypothesis being plausible means that the pvalue is greater than the significance level, that is, greater than 0.05. So the correct answer is given by option b.
