mean. Into what range must a candidate’s cholesterol level be in order for the candidate to be included in the study? Solar energy is considered by many to be the energy of the future. A recent survey was taken to compare the cost of solar energy. Results of the survey revealed that the distribution of the amount of the monthly utility bill of a 3-bedroom house using gas or electric energy had a mean of $91 and a standard deviation of $13. Assuming the distribution is symmetric; would you expect to see a house using gas or electric energy with a monthly utility bill of $182.00?
