Example 19.10 Suppose that a company has conducted a field survey covering 200 respondents. Apartfrom other questions, it asked the respondents to indicate on a 5-point scale how much the durability ofa particular product is important to them. The respondents indicated as follows:Very important50Somewhat important.60Neither important nor unimportant2040Somewhat unimportantVery unimportant30Total respondents200We have been asked to use the Kolmogorov-Smirnov test to test the hypothesis that there is nodifference in importance ratings for durability among the respondents.

Please make sure the response is specific to the variables in this problem: Imagine that you are interested in studying the working habits of young adults. You hypothesize that persons first married in their twenties tend to work an average of 5 hours more per week than persons not first married in their twenties. After conducting a survey study, you find a relationship between participants’ age at first marriage and the number of hours worked per week. What three conditions must be satisfied for you to have established a causal connection?

1. A salesman for home insulation conducted a telephone poll of the first 25 people from his firm's client list. He asked each person this question: Home insulation is one of the best ways to reduce your monthly heating bill. On a scale of 1 to 7, where 1 is unimportant and 7 is extremely important, how important is it to you to have adequate home insulation? All but one responded with a rating of 5 or above. The salesman wrote to his manager that "96% of people in our town think that insulation is very important." Are the survey results valid? Why or why not? (Hint: Discuss sample size, question, sample technique, and survey technique)
6. Accidents on highways are one of the main causes of death or injury in developing countries and the weather conditions have an impact on the rates of death and injury. In foggy, rainy, and sunny conditions, 1/4, 1/8, and 1/21 of the accidents result in death, respectively. Sunny conditions occur 60% of the time, while rainy and foggy conditions each occur 20% of the time. Given that an accident without deaths occurred, what is the conditional probability that it was foggy at the time?
Hello, Could you please go through all of the following question. Thank you.
You conducted additional studies with these men and found the following: The RR for those who drank one drink per day was 1.50 (95% CI:1.32-1.67) in comparison to the abstainers. For those men who drank three or more drinks per day the RR compared to the abstainers was 4.20 (95% CI 2.68-5.85). Which one of Hill’s criteria does this illustrate? Explain.
4. A teacher gives a reading skills test to a third-grade class of n = 25 at the beginning of the school year.

1. A new drug for pain relief is being tested within a given palliative care population. The new drug is being compared to an already approved pain relief drug that is commonly used in providing palliative care to patients who experience chronic severe pain. Assume the patients are asked to rate the pain on a scale from 1 to 10, and the data presented below was obtained from a small study designed to compare the effectiveness of the two drugs. Set up and interpret the results of a Mann-Whitney U test with an alpha of .05.Pain Rating as Reported by PatientsOld Drug 1 2 2 4 6New Drug 1 2 2 3 7Total Sample(Ordered Smallest to Largest)RanksOld Drug New DrugOld Drug New Drug Old Drug New Drug1 1 1 1 1.5 1.52 2 2 2 4.5 4.52 2 2 2 4.5 4.5
