Data on residential energy consumption per capita (measured in million BTU) had a mean of 70.8 and a standard deviation of 7.3 for the states east of the Mississippi River. Assume that the
distribution of residential energy use is approximately unimodal and symmetric. Complete parts (a) through (d) below.
a. Between which two values would you expect to find approximately the middle 68% of the per capita energy consumption rates?
Between and million BTU
(Round to one decimal place as needed. Use ascending order.)

c. If an eastern state had a per capita residential energy consumption rate of 55.1 million BTU, would this be considered unusual? Explain.
OA. Yes, because 55.1 million BTU is not more than two standard deviations from the mean.
OB. Yes, because 55.1 million BTU is more than two standard deviations from the mean.
OC. No, because 55.1 million BTU is not more than two standard deviations from the mean.
OD. No, because 55.1 million BTU is more than two standard deviations from the mean.
d. New Jersey had a per capita residential energy consumption rate of 65.8 million BTU, would this be considered unusually low? Explain.
OA. No, because 65.8 million BTU is more than two standard deviations below the mean.
OB. Yes, because 65.8 million BTU is not more than two standard deviations below the mean.
OC. No, because 65.8 million BTU is not more than two standard deviations below the mean.
OD. Yes, because 65.8 million BTU is more than two standard deviations below the mean.
