Should you continue this hypothesis test? calculate the test statistic. First, calculate the sample mean and sample standard deviation using StatCrunch and do not round these values. Next, show the work necessary to obtain the test statistic by typing all your steps and providing the resulting test statistic. Do not round anything during the calculation. Then, round the test statistic to three decimal places after you complete the calculation.Probabilty of P(Z ≤ 1.0)5
