A random sample of 50 students at a large high school resulted in a 95% confidence interval for the mean numbers of hours of sleep per day of (6.7, 7.5). Provide the interpretation for this confidence interval?
solution
given that
n=50
lower limit=6.7
upper limit=7.5
At 95% confidence interval estimate of the mean of large high
school result is fall between lower limit=6.7 and upper
limit=7.5
