Statistics

Here is one that I really would like to know if I have the right answers-
In data from a sample of 400 cases, a variable has a 95% confidence interval
of 54.3 to 54.7 find the following:
Mean, standard deviation and standard error.
I have come up with the following
Mean 54.5 Standard Deviation 2.04 and standard error .1020?

One more thing- could someone tell me with the large F means when you have a histogram table?

Thanks

This is only a guess = could F stand for "frequency?"

Correct the first part! Good job!
