Use the following results from a test for marijuana use, which is provided by a certain drug testing company. Among 148 subjects with positive test results, there are 24 false positive results; among 159 negative results, there are 5 false negative results. If one of the testsubjects is randomly selected, find the probability that the subject tested negative or did not use marijuana. (Hint: Construct a table.)The probability that a randomly selected subject tested negative or did not use marijuana is.(Do not round until the final answer. Then round to three decimal places as needed.)C

Assume that a randomly selected subject is given a bone density test. Those test scores are normally distributed with a mean of 0 and a standard deviation of 1. Draw a graph and find the bone density test scores that can be used as cutoff values separating the lowest 10% and highest 10%, indicating levels that are too low or too high, respectively. Sketch the region containing the lowest 10% and highest 10%. Choose the correct graph below. OA. -Za Za Q The bone density scores are ☐ OB. -Za Za (Use a comma to separate answers as needed.
