The difference in hours of sleep (reduced screen time week – usual routine week) was recorded.The sample (n = 400 ) had a mean increase in sleep of 0.8 hours with a standard deviation of 1.2 hours.Construct a 95% confidence interval for the mean difference in hours of sleep.Interpret the confidence interval in words.Is there evidence that reducing screen time before bed is effective? Explain.Would you recommend this intervention based on these results? Why or why not?*Show work to receive full credit. This includes writing the correct formula, plugging in the values, and solving.
