A store sells bags of candy that weigh 2lb according to the packaging. The weights of 15 randomly selected bags are found to have a sample mean of 1.92 with a sample standard deviation of 0.2. If the test statistic is t=−1.55 and the alternative hypothesis is Ha:μ<2, what is the p-value range for the appropriate hypothesis test?
