Betty and Bob test The Null Hypothesis that the population Mean is 60. They randomly sample 19 numbers from the population and find the Sample Mean is 67 and the Sample Standard Deviation is 15. Should they Accept or Reject the Null Hypothesis? ____________ Find the Level of Confidence, P, where it is unclear whether to Accept or Reject the Null Hypothesis; that is where 60 is an end point of the interval. P = _______________
