An investigator is conducting a hypothesis test. If the hypotheses considered are: H0: The average battery life of a cell phone from a certain company is 45 hrs. Ha: The average life time of cell phone batteries for a given company is less than 45 hours. Knowing that from a sample of 36 of these cell phones, the average battery life time was 44 hrs. And complying with the appropriate steps to carry out the hypothesis test, the decision reached by the researcher with a significance level of 5% was to reject the Null hypothesis.
