Hi,
134 golfers: m = 87.43  and s = 4.53
(A) Find the 99% confidence interval of the mean score for all 134 golfers.
  ME = {{{2.58(4.53/sqrt(134))}}}
the 99% confidence interval:
  87.43 - ME < {{{mu}}} < 87.43 + ME
99% confidence interval of the mean score for all golfers if this is a sample of 105 golfers
  ME = {{{2.58(4.53/sqrt(105))}}}
  87.43 - ME < {{{mu}}} < 87.43 + ME
(C) Which confidence interval is smaller and why
  larger sample has a smaller confidence interval as the ME is smaller
{{{sqrt(134)>sqrt(105)}}}
