following statements 4. A researcher wishes to determine whether the average age of people in a province is really 56.3 years. A sample of 35 residents has án average age of 53.2 years. Use x = 0.05 and assume that the ages are normally distributed with a standard deviation of 2,1 years. 5. A cable brand claims to have a breaking strength of at least 900 pounds with a standard deviation of 13 pounds. A company researcher selects a sample of 29 cables and finds out that the average breaking strength is 825.3 pounds. Assume that the breaking strength of the cables is normally distributed. If the level of significance is set to a = 0.05 Direction: For each given situation in test B, determine the hypotheses, test statistic and rejection region.
