. A sample mean, sample standard deviation, and sample size are given. Use the one-mean t-test to perform the required hypothesis test about the mean, μ, of the population from which the sample was drawn. Use the critical-value approach. Sample mean = 7.1                 s = 2.3             n = 18              α = 0.01 H0: µ = 10 H1: µ < 10 The decision is to  the null hypothesis. (Enter R if you reject and enter F if you fail to reject)
