A group was tested for drugs. The table shows the results of the test along with actual drug use. Let D = event “Used Drugs”, N = event “No Drug Use”, + be “Test positive”, and finally – be “Test negative”Round each answer to 4 decimal places. (D or +) = [a] (N and +) = [b] (N | +) = [c] (+ | N) = [d]

The table below shows the head size of 30 male soldiers in inches. The head size was measured by wrapping a tape measure around the solder’s head. Construct a stem plot for the head size data set. If a stem has no corresponding leaves, put a dash, like this – .                                     Stems Leaves 24 [a] 25 [b] 26 [c] 27 [d] 28 [e] 29 [f] 30 [g] 31 [h] 32 [i]

Read and answer the following question. If a calculation is not possible, type NA. The population of weights for men attending a local health club is normally distributed with a mean of 183 lbs and a standard deviation of 26 lbs. An elevator in the health club is limited to 35 occupants, but it will be overloaded if the total weight is in excess of 6860 lbs.Assume that there are 35 men in the elevator. What is the average weight per man that, beyond which, the elevator would be considered overloaded? average weight = [a] lbs What is the probability that one randomly selected male health club member will exceed this weight? P(one man exceeds) = [b] round to 2 decimal places If we assume that 35 male occupants in the elevator are the result of a random selection, find the probability that the elevator will be overloaded? P(elevator overloaded) = [c] round to 4 decimal places

The following data set outlines the scores students had on an Algebra test. i) Fill in the frequency table below. Score Frequency 40-49  [a] 50-59  [b] 60-69  [c] 70-79  [d] 80-89  [e] 90-99  [f]   ii) Draw a histogram on your scratch paper by drawing a horizontal line segment the top of each histogram bar.Optional: Then draw vertical line segments for the sides. You will submit your scratch paper at the end of the test.
