Consider the following hypotheses: H0: μ = 120 HA: μ ≠ 120 The population is normally distributed with a population standard deviation of 46. (You may find it useful to reference the appropriate table: z table or t table) a-1. Calculate the value of the test statistic with x−x− = 132 and n = 50. (Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.)
