ounces. Suppose that in a particular sample of 50 packages, the mean amount dispensed is 8.172 ounces, with a sample standard deviation of 0.058 ounce. Complete parts (a) and (b). Click here to view page 1 of the critical values for the t Distribution. Click here to view page 2 of the critical values for the t Distribution. a. Is there evidence that the population mean amount is different from 8.17 ounces? (Use a 0.10 level of significance.) State the null and alternative hypotheses. \[ \begin{array}{ll|l|} \mathrm{H}_{0}: \mu & \boldsymbol{\nabla} & \square \\ \mathrm{H}_{1}: \mu & \boldsymbol{\nabla} & \square \end{array} \] (Type integers or decimals.) Identify the critical value(s). The critical value(s) is(are) \( \square \) . (Round to four decimal places as needed. Use a comma to separate answers as needed.) Determine the test statistic. The test statistic is \( \square \) . (Round to four decimal places as needed.) State the conclusion. \( \square \) \( \mathrm{H}_{0} \). There is \( \square \) evidence to conclude the population mean amount is different from 8.17 ounces. b. Determine the p-value and interpret its meaning. The p-value is \( \square \) (Round to four decimal places as needed.) Interpret the meaning of the p-value. Choose the correct answer below. A. The p-value is the probability of not rejecting the null hypothesis when it is false. B. The p-value is the probability of obtaining a sample mean that is equal to or more extreme than 0.002 ounce below 8.17 if the null hypothesis is false. C. The p-value is the probability of obtaining a sample mean that is equal to or more extreme than 0.002 ounce above 8.17 if the null hypothesis is false. D. The p-value is the probability of obtaining a sample mean that is equal to or more extreme than 0.002 ounce away from 8.17 if the null hypothesis is true.
