Suppose a random sample of 150 universities is used to test the null hypothesis that the average number of spam emails economics graduate students receive in a month is 30.48. The value of the test statistic is found to be 2.54. If the null is tested against the alternative hypothesis that the number of spam emails is not 30.48, the smallest significance level at which you can reject the null hypothesis is .0111 . (Round your answer to four decimal places.) If the null is tested against the alternative hypothesis that the number of spam emails is more than 30.48, the smallest signicance level at which you can reject the null hypothesis is (Round your answer to four decimal places.)
