A reseаrcher is cоmpаring аverage mоnthly electricity usage (in kilоwatt-hours) for households in two regions of Virginia: Northern Virginia and Central Virginia. A sample of households in each region were taken: Northern Virginia: sample size of 64 mean was 920 kWh standard deviation was 120 kWh Central Virginia: sample size of 81 mean was 860 kWh standard deviation was 135 kWh a. Construct a 95% confidence interval for the true mean monthly electricity usage for both Northern Virginia households and Central Virginia households (2 separate intervals). b. Based on your confidence intervals, compare the two regions. Is there a meaningful difference in average electricity usage? Write a complete conclusion in context.
