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 138 adolescents in substance abuse treatment used medical marijuana in the last six months was 99.92. Assume the population standard deviation is 27 days. Complete parts (a) through (d) below. a. Find a 95% condence interval for the mean number of days, p, of diverted medical marijuana use in the last 6 months of all adolescents in substance abuse treatment. The 95% condence interval for p is from days to days. (Round to two decimal places as needed.) b. Find a 90% confidence interval for the mean number of days, p, of diverted medical marijuana use in the last 6 months of all adolescents in substance abuse treatment. The 90% condence interval for u is from days to days. (Round to two decimal places as needed.) c. Draw a graph to display both confidence intervals. Choose the correct graph below. {j A.

Which confidence interval yields a more accurate estimate of u? Explain your answer. The confidence interval is a more accurate estimate, because it is than the confidence interval
