QuestionYou wish to test the following claim (Ha)\left(H_{a}\right) at a significance level of α=0.02\alpha=0.02. Ho:μ=82.2Ha:μ<82.2\begin{array}{c} H_{o}: \mu=82.2 \\ H_{a}: \mu<82.2 \end{array}
You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n=18n=18 with mean M=78.3M=78.3 and a standard deviation of SD=18.2S D=18.2.
What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = \square What is the p-value for this sample? (Report answer accurate to four decimal places.) p -value == \square
