Question
(c) Determine and interpret a 95% confidence interval for the mean amount of time people age 15 or older spend eating and drinking each day.
(c) Determine and interpret a 95% confidence interval for the mean amount of time people age 15 or older spend eating and drinking each day.
Assuming that the sample standard deviation of time spent eating and drinking each day is .65 hours, construct and interpret a 95% confidence interval for the mean time spent eating and drinking each day.
While either technology or by hand methods can be used to compute this confidence interval, for this problem use technology. 95% confidence interval based on the statistics from this sample using the t-distribution. Note that the sample size must be large (ngreater than or equals30) or the population must be normally distributed.
Determine the lower bound on the 95% confidence interval with x 1.69, s =.65, n=1008
Determine the upper bound on the 95% confidence interval
