35 households were selected as part of a study on electricity usage and the number of kilowatt-hours was recorded for each household. . In a very large study in the first quarter of the previousyear, with a standard deviation of usage of 81 kWh. What is the required number of observationsnecessary to estimate the true average electricity usage per household with 95% confidence thatthe sample average within 25 KWhr of the true average?
