7. The following hypothesis test for the mean is being done: Ho: H = 50 H1: H# 50 A sample is taken and produces a value of the sample mean of x = 46.3. This value is significant at the .05 level of significance. a. (8 pts.) Will this value of the sample mean necessarily also be significant at the . 10 level? Explain. b. (5 pts.) Suppose the value of x had been 57.0 instead of the above value. Which of the two values of the sample mean mentioned above (46.3 or 57.0), which would have the smaller p- value? Explain
