To investigate an alleged unfair trade practice, the FTC takes a random sample of 16 "5-ounce" candy bars. The mean of the sample weights is 4.85 ounces, and the sample standard deviation is 0.1 ounce. Test the hypotheses: H0 : μ ≥μ≥ 5 Ha : μμ < 5 At the 5% significance level.

Bases on the results, does the FTC have grounds to proceed against the manufacturer for unfair practice of short-weight selling?
