Since the p-value is given as 0.05 and no significance level is provided, we can assume it to be 0.05. As the p-value is greater than the significance level, we fail to reject the null hypothesis. Hence, we can conclude that there is insufficient evidence to suggest that the population variances in the amount of time for the two hotels are different. Therefore, the correct answer is C - The null hypothesis is not rejected.
