The CEO of a major tech company was interested in developing a new type of tablet. However, before she decided how much money she wanted to invest in research and development, she wanted to conduct a survey to determine the average amount of time a person spends on their tablet each day. She had her employees conduct a survey of 1000 randomly selected individuals who owned tablets. As part of the survey, they found that those 1000 individuals spent an average of 1.20 hours per day on their tablets. Assume the true standard deviation amount of time that someone spends on their tablet per day is 2.66 hours. Use this information to construct and interpret a 93% confidence interval for the true average amount of time a person spends on their tablet each day. Make sure that you are addressing the following in your response. . Check any and all relevant assumptions and state specifically how they are/aren't satisfied - State the desired confidence interval (round any values in your interval to 2 decimal places, Le. 54.321 would be rounded to 54.32) • Interpret the interval in context of the scenario provided.
