An insurance company offers four different deductible levels-none, low, medium, and high-for its homeowner's policyholders and three different levels–low, medium, and high-for its automobile policyholders. The accompanying table gives proportions for the various categories of policy- holders who have both types of insurance. For example, the proportion of individuals with both low homeowner's deductible and low auto deductible is .06 (6% of all such individuals). Homeowner's Auto N M H .04 .06 .05 .03 M .07 .10 .20 .10 H .02 .03 .15 .15 Suppose an individual having both types of policies is ran- domly selected. a. What is the probability that the individual has a medium auto deductible and a high homeowner's deductible? b. What is the probability that the individual has a low auto deductible? A low homeowner’'s deductible? c. What is the probability that the individual is in the same category for both auto and homeowner's deductibles? d. Based on your answer in part (c), what is the probability that the two categories are different? e. What is the probability that the individual has at least one low deductible level? f. Using the answer in part (e), what is the probability that neither deductible level is low?

The quality department at an electronics company has noted that, historically, 91% of the units of a specific product pass a test operation, 6% fail the test but are able to be repaired, and 3% fail the test and need to be scrapped. Due to recent process improvements, the quality department would like to test if the rates have changed. A recent sample of 500 parts revealed that 473 parts passed the test, 20 parts failed the test but were repairable, and 7 parts failed the test and were scrapped. (You may find it useful to reference the appropriate table: chi-square table or table)a. Choose the appropriate alternative hypothesis for the test.
A school district started using a new criteria for selecting which students entered their "accelerated" math track, starting in 6th grade. The study found that under the new criteria about 75% of the students in the district were eligible for accelerated math in 6th grade, but that from one year to the next only about 2/3 of the students stayed in the accelerated track. a) Assuming that everyone who is eligible enrolls the first year, make a TABLE that shows the percent of the students in the district that would be expected to be enrolled in the accelerated track each year from 6th grade until 10th grade. Please show the work you used to fill in your table. b) Considering that from one year to the next about 2/3 of the students stay in the accelerated track, is there a grade level in which you'd expect about 1/10 as many students in the accelerated track as there were in 6th grade? Does the number of students in the accelerated track in 6th grade affect your answer? Please show your…
