In astudy, the mean number of days that 132 adolescents in substance abuse treatment used medical marijuana in the last 5 months was 114.17. Assuming the population standard deviation is 29 days, a 90% confidence interval for the mean number ofdays, , of medical marijuana use in the last 5 months of all adolescents in substance abuse treatment is from 110.02 days to 118.32 days; thisinterval's margin of error is 4.15 days.
a. The mean number of days that 33 adolescents in substance abuse treatment used medical marijuana in the last 5 months was 111.02. Find a 90% confidence interval for based on that data.
The 90%confidence interval for u is from days---------? to day-----------?
Whichconfidence interval yields a more accurateestimate of u? Explain
The ?confidence interval is more accuratebecause it? ------Than the?------confidence interval
