Answer:
A. Reject the null hypothesis because p-value < 0.005 is less than the significance level a = 0.05
Step-by-step explanation:
In hypothesis test, test statistic calculated and it's p-value is compared against the significance level. If it is less than the significance level, the result is significant at the given significance level. In this case one can reject the null hypothesis in favor of the alternate hypothesis.
In this example Katherine find test statistic -3.39, and p-value < 0.005. Thus she can conclude there is significant evidence that the population mean peak power is less than the advertised amount
3/5 divided by 1/3 is 9/5 or 1 4/5
Therefore the answer is 1 and 4/5
