In order to conduct a hypothesis test of the population mean, a random sample of 20 observations is drawn from a normally distributed population. The resultingsample mean and thesample standard deviation are calculated as 11.9 and 1.8, respectively.  The hypotheses are

H₀: μ ≤ 11.3, H_A: μ > 11.3

(a) Calculate the value of thetest statistic.(Round your answer to 2 decimal places.)

(b) Give thep-value (Round to three decimal places.)
