In a hypothesis test with the null and alternative hypotheses Ho: 280 and H₁ μ< 80, a random sample of 98 elements selected from the population produced a mean of 75.9. Assume that o = 23.2, and that the test is to be made at the 1% significance level. What is the value of the test statistic, z, rounded to three decimal places?
