Aresearcher has collected n = 1000 random water samples from a freshwater lake and the calcium concentration (milligrams per liter) were measured. a 95% confidence interval for the population mean calcium concentration was found to be [0.49, 0.82]. state a decision for the hypothesis test below (i. e. reject h0 or fail to reject h0) using this 95% confidence interval when testing the hypothesis at the α = 0.05 level. h0 : µ = 0.60 vs. h1 : µ 6= 0.60.
