1) The distribution of the home-prices lies between $50,000 and $350,000. The distribution is right-skewed
(mean>mode; K3 = 0.8761599) and leptokurtic (K4 = 0.7598074). The distribution is like that of the income

1) The conditions necessary to create confidence intervals are:
a) The sampling method is SRS.
b) The distribution is approximately normal.
c) The distribution is large enough.
All the above three criteria are met. Hence, the confidence interva
