How do I fill out this table? I figured out the sample mean price based off of my previous spreadsheet...I am having problems with the 95% confidence interval and writing using interval notation.

1- n= 10 , sample mean is 1245400, population standard deviation is $704,500...

2- n=30 , sample mean is 1226903.226, pop stand dev is same as above

3- n=50 , sample mean is 1190088.235, same as above

4- n=100, sample mean is 1176192.95, same as above
