- A forensic psychologist who specializes in personality traits and their relationship to crime hypothesizes that those higher in the trait of thrill-seeking will be more likely to commit burglaries. The scores on a measure of thrill seeking and the number of arrests for burglary (and the corresponding z-scores) were as follows for a group of convicted felons from urban communities: THRILLSEEK # ARRESTS Z-THRILLSEEK Z-ARRESTS 36 10 2.55 1.87 29 9 0.89 1.63 27 8 0.41 1.15 27 6 0.41 0.42 26 5 0.18 0.30 26 3 0.18 -0.54 26 4 0.18 0.06 25 4 -0.06 0.06 25 4 -0.06 0.06 25 5 -0.06 0.18 25 5 -0.06 0.18 25 5 -0.06 0.18 23 3 -0.53 -0.54 23 1 -0.53 -1.75 22 2 -0.77 -1.15 14 1 -2.67 -1.75 Using α of .05, what has the researcher found?

Weekly gross sales for Cchem has a mean of $1 million and standard deviation of $0.2 million; the distribution of sales is highly right-skewed. One week’s sales are independent of the sales in any other week. Use this information to answer questions 5 to 6 below. What is the probability that sales for the week of October 5, 2009 will be more than $1.25 million? In order for Cynthia to receive a bonus, Cchem’s annual sales must exceed $53 million. What is the probability that Cynthia will receive a bonus for the fiscal year starting in 2010? Assume there are 52 weeks in a year.An airline operates a call center to handle customer questions and complaints. The airline monitors a sample of calls to help ensure that the service being provided is of high quality. Ten random samples of 100 calls each were monitored under normal conditions.

- Consider an experiment for patients who underwent CPR for a heart attack and then was sent to the hospital. Patients were randomly divided into a treatment group where they received a blood thinner or the control group where they did not. We're interested in understanding what proportion of patients survived in the first 24 hours in the hospital. Here's the data: Control Treatment Survived 11 14 Died 39 26 With the help of Mathematics and R Studio: Conduct a (full) hypothesis test to determine if the treatment group survived at a higher rate than the control group.An airline operates a call center to handle customer questions and complaints.
