Suppose that a researcher decides that he MUST obtain a Type 1 error level of no more than 0.01 in order to reject the null hypothesis. After analyzing his data he finds that the results are significant at p = 0.05 but not at p = 0.01. If he is not able to change the maximum allowed Type 1 error level, then the researcher should   Question 5 options:   retain the null hypothesis because 0.05 is greater than 0.01.   retain the null hypothesis because 0.05 is merely sampling error.   reject the null hypothesis because 0.05 is close to 0.01.   reject the null hypothesis because 0.05 is greater than 0.01.
