In a hypothesis test with the null and alternative hypotheses Ho: u < 45 and H:u > 45, a random sample of 69 elements selected from the population produced a mean of 47.3. Assume that a = 6.9, and that the test is to be made at the 2.5% significance level. What is the value of the test statistic, z, rounded to three decimal places?
