A sample of n sludge specimens is selected and the pH of each one is determined. The one-sample t test will then be used to see if there is compelling evidence for concluding that true average pH is less than 7.0. What conclusion is appropriate in each of the following situations? a. n = 6, t= -2.3, a=.05b. n = 15, t= -3.1, a =.01c. n =12, t = -1.3, a =.05d. n =6, t = .7, a = .05e. n = 6, xÌ = 6.68, s/ân = .0820
