Solve correctly for A-D in the picture
![An issue with legalization of medical marijuana is "diversion", the process in which medical marijuana prescribed for one person is given, traded, or sold to someone who is not registered for medical marijuana use. The mean number of days that 127 adolescents in
substance abuse treatment used medical marijuana in the last six months was 103.16. Assume the population standard deviation is 26 days. Complete parts (a) through (d) below.
a. Find a 95% confidence interval for the mean number of days, µ, of diverted medical marijuana use in the last 6 months of all adolescents in substance abuse treatment.
The 95% confidence interval for u is from days to
days.
(Round to two decimal places as needed.)
b. Find a 90% confidence interval for the mean number of days, µ, of diverted medical marijuana use in the last 6 months of all adolescents in substance abuse treatment.
