A pharmaceutical
company is considering marketing a new local medicine. The effective time of the existing medicine currently produced by the
company has a normal distribution with a mean of 7.4 minutes and a standard deviation of 1.2 minutes. The chemistry of the new medicine is such that the effective time should be normally distributed with the same standard deviation, but the mean effective time may be lower. If it is lower, the
company will market the new medicine; otherwise, they will continue to produce the existing one. A sample of size 36 results in a sample mean of 7.1 minutes. A hypothesis test will be done to help make the decision.
Form appropriate hypotheses for the test above. A. Ho: = 7.4 minutes 7.4 minutes HA: B. Ho: >7.4 minutes HA: US 7.4 minutes C. Ho: 27.4 minutes HA: <7.4 minutes D. Ho: HS 7.4 minutes HA: >7.4 minutes
