(a) Determine the interval (smallest value to largest value) within which you would expect 99.7% of such sample means to lie.
(b) What is the amount of deviation from the mean for a sample mean of 45.3?
(c) What is the maximum deviation you have allowed for in your answer to part (a)?
(d) How is this maximum deviation related to the standard error of the mean?

2 multiples of the standard error
3 multiples of the standard error
4 multiples of the standard error
