A random sample of 50 households was selected as part of a study on electricity usage, and the number of kilowatt-hours (kWh) was recorded for each household in the sample for March 2019. The average usage was found to be 455kWh with a standard deviation of 81kWh.A one-sample t-test is to be done to determine if the true mean electricity usage of households in March 2019 is 500kWh.Use the drop-down menus to identify if the following conditions for this test are satisfied or not.The sample is representative of the population.AnswerThe sampling distribution of the sample mean is normal.
