The claim is that weights (grams) of quarters made after 1964have a mean equal to 5.670 g as required by mint specifications. The sample size is n=39 and the test statistic is t=−3.091. Use technology to find the P-value. Based on the result, what is the final conclusion? Use a significance level of 0.10.
