1.Ho: ? = 120Ha: ? ? 120 A random sample of size is 12 is taken from the target population. Suppose you are testing the following hypothesis: Here is this sample. 108.98   127.46  111.56152.22   107.26     75.71111.45    93.32    128.58110.59    91.97    135.11 The ? = 0.05. Should the Ho be rejected? 2. Suppose you want to estimate, with 95% confidence, the population mean force required to break the insulator to within +/- 25 pounds. On the basis of a study conducted the previous year, you believe that the standard deviation is 100 pounds.  Calculate the required sample size.
