researcher is conducting a study to examine what factors influence older adult's Binge Drinking behaviors, with binge drinking being consuming 4 or more drinks at a time. They gathered data from 1,666 older adults in the US and asked them how many days they drank four or more drinks in the past 12 months. They found that on average older adults in their sample drank 2.62 days per week with a standard deviation of 11.52. What is the confidence interval for the mean number of binge drinking days in the entire US population? Construct a 95% confidence interval around the point estimate. Remember to: (1) choose an alpha, 2) find the z score & 3) calculate the confidence interval. What is the upper limit of the confidence interval, rounded to 2 decimals? How would you interpret the confidence interval you just calculated?
