QUESTION 1A manufacturer claims that the average capacity for a certain type of battery is 140 ampere-hours. An independent consumer protection agency wishes to test the credibility of themanufacturer's claim. It measures the capacity of ten randomly selected batteries from acurrent production batch. The results, in ampere-hours, are as follows:138.8 139.1 141.1 139.7 137.4 140.9 138.2 139.2 136.7 141.8i) Find the point estimate of the mean and variance of the battery capacity.

Given data is,138.8 , 139.1 , 141.1 , 139.7 , 137.4 , 140.9 , 138.2,139.2 , 136.7 , 141.8sample…

A statistical program is recommended. Electric power consumption is measured in kilowatt-hours (kWh). The local utility company offers an interrupt program whereby commercial customers that participate receive favorable rates but must agree to cut back consumption if the utility requests them to do so. A certain company cuts back consumption at 12:00 noon Thursday. To assess the savings, the utility must estimate the company's usage without the interrupt. The period of interrupted service was from noon to 8:00 p.m. Data on electric power consumption for the previous 72 hours are available.
