Question: A certain commodity is known to have prices that are stable through tiMeand do not change according to any known trend. Price, however, does change from day to day in a random fashion. If the price is at a certain level one day, it is as likely to be at any level the next day within some probability bounds approximately given by the normal distribution. The mean daily price is believed to be $14.25. To test the hypothesis that the average price is $14.25 versus the alternative hypothesis that it is not $14.25, a random sample of 16 daily prices is collected. The results are a sample average of $16.50 and a sample standard deviation of $5.80. Using a significance level of 5%, can you reject the null hypothesis? Show the test statistic and the p-value and explain your answer.
