Question

Netflix Addiction. A research was conducted to assess the impact of Netflix on students’ academic performance. A random sample of 300 students resulted in a sample mean of 10.7 hours (watched per week) with a population standard deviation of 4.2 hours. Calculate a 99 % confidence interval for the data (round your answer to 2 decimal places). Show a complete solution and explain the meaning of the confidence interval.

Answer 1

Set up the confidence interval. Plug in the given values for the variables.

[μ ± z*(σ/√n)] = [10.7 ± 2.576*(4.2/√300)] = [10.08 , 11.32]

We are 99% confident that students watched Netflix between 10.08 and 11.32 hours per week.
