A random sample (n=16) is obtained from a population with a mean of 70, and a treatment is administered. After treatment, the sample mean is found to be M = 75 and the sample variance is 81. Conduct a one-sample t test (alpha = .05, two-tailed). a) State the null and alternative hypotheses in SYMBOLS only. Null: Alternative: b) What is the critical t? c) What is the observed t-statistic?
