A school administrator wants to know what
proportion of the approximately
80,000 teachers in their state have a Master's
degree. The administrator takes an
SRS of 100 teachers from a statewide database
containing every teacher, and they find
65 teachers in the sample have a Master's
degree.
Based on this sample, the
administrator construct 99% confidence interval
for the proportion of teachers in the state with a
Master's degree (0.55, 0.65)
The point estimate for this interval is:
0.65
O 0.60
