A 95% confidence interval for the mean number of monthly customer visits to a grocery store is 28,000 to 32,000 customers. Which of the following is an appropriate interpretation of this confidence interval? A.
1、The 95% confidence interval for the sample mean is -4.56 to 3.27. The null hypothesis is that the sample mean is equal to zero. The alternative hypothesis is that the sample mean is not equal to zero (two-tail test). The null hypothesis most appropriately should be:【单选题】 A. ...
