How many tissues should the kimberly clark corporation package of kleenex contain? researchers determined that 60 tissues is the mean number of tissues used during a cold. suppose a random sample of 100 kleenex users yielded a mean of 52 tissues used during a cold with a standard deviation of 22. suppose the alternative you wanted to test was h1: µ < 60. if the critical value in this situation at an α = .05 is -1.6604, when should we reject the null?
