Recently, a drug testing company provides a test for marijuana usage. Among 200 tested subjects, results from 23 5 points usage. subjects were wrong. Suppose you want to estimate the true proportion of wrong testing results for all marijuana (a) [1] Give a point estimate of the true proportion of wrong testing results for all marijuana usage. (b) [1] Verify that the sample is sufficiently large tore it to construct a confidence interval for that proportion. (c) [1] Construct a 90% confidence interval for the proportion of wrong testing results for all marijuana usage. (d) [1] Interpret the result in part (c). (e) [1] A researcher claims that the proportion of wrong testing results for all marijuana usage is 0.13. Does your solution from (c) support this claim? Give the reason. Attach File
