H0: d Ha: d Use a .05 level of significance. What is the p-value? The p-value is Can you conclude that the population means differ? Which category, groceries or dining out, has a higher population mean annual credit card charge? What is the point estimate of the difference between the population means? $ What is the 95% confidence interval estimate of the difference between the population means (to the nearest whole number)?
