In a hypothesis test with hypotheses Ho : µ = 90 and H1 : µ # 90, a random sample of 103 elements selected from the population produced a mean of 94.3. Assume that o = 22.1, and that the test is to be made at the 5% significance level. What is the value of the test statistic, z, rounded to three decimal places?
