A random sample of 10 houses in a particular area, each of which is heated with natural gas, is selected
and the amount of gas (therms) used during the month of January is determined for each house. The
resulting observations are 103, 156, 118, 89, 125, 147, 122, 109, 138, 99. Let mu denote the average gas
usage during January by all houses in this area.
a) Compute a point estimate of μ
b) Find a 95% Confidence Interval of the point estimate of μ
