As a stock analyst, your boss, Jerry, has asked you to compile some information on stock of Southern Infrastructure Corporation including a 95% confidence interval for the mean daily return that he needs to include in a report to senior management. He says that he is also not sure exactly what a 95% confidence interval means and would like you to add an explanation.
You have been following the share price of Southern Infrastructure Corporation and have recorded the daily return (as a percentage) for the last 120 days. The data is presented here:
mean=44.2020
Historically, the standard deviation in daily return for this stock is 1.0%.
Complete the report to your boss. Give your numeric answers to 3 decimal places.

Dear Jerry,
Here are the results gathered from the collected data:
Assuming a population standard deviation in daily return of 1.0%, the 95% confidence interval for the mean daily return is:
a) ? ? ?
b)This means that
approximately 95% of sample means will be within the interval given above
using a process that gives correct results in 95% of cases, the population mean daily return is within the interval given above
the population mean daily return is definitely within the interval given above
on approximately 95% of days in a given period the stock makes a return within the interval given above
