Consider a paint-drying situation in which drying time for a test specimen is normally distributed with s = 6. the hypotheses h0: µ = 74 and ha: µ < 74 are to be tested using a random sample of n = 25 observations.(a) how many standard deviations (of x) below the null value is x = 72.3? (round your answer to two decimal ) if x = 72.3, what is the conclusion using a = 0.01? (round your answers to two decimal places.)test statistic z =critical value z =what can you conclude?
