A university is advertises that average student debt for any student completing a bachelor's at their campus is $30,000. Students feel that they are spending too much on fees and feel the average debt is much higher. A student statistician surveys 200 students and the average debt of the students is $31,000 with a standard deviation of $1,800. At the 5% significance level, determine if the average debt is more than $30,000 for any student that would attend the university and complete a bachelor's. Give the hypotheses. Null: The average student debt is $30,000. Alternative: The average debt is lower than $30,000. O Null: The average student debt is $30,000. Alternative: The average debt is higher than $30,000. Null: The average student debt is $30,00O. Alternative: The average debt is not $30,000.

If a fictional treatment costs a total of $45,000 at today’s value and increases a person’s quality of life from 0.5 to 0.6 for the remainder of the person’s life from age 70 onward, and the person’s expected life span increases from 73 to 75, what is the total gain in QALYs (Quality-adjusted Life Years), and what is the ICER (Incremental Cost-effectiveness Ratio)?
Only the question 5 and 6 need to be resolved. Others have been reaolved already. Question: sample of 15, 10 years old children was taken to study whether watching television reduces the amount of physical exercise, causing weight gains. The number of kilograms each child was overweight by was recorded (a negative number indicates the child is underweight). In addition, the number of hours of television viewing per week was also recorded. These data are listed in the table below. Television(hours) 42 34 25 35 37 38 31 33 19 29 38 28 29 36 18 Overweight (Kg) 8 3 0 0 6 6 3 3 -4 4 4 2 1 6 -3 Use an appropriate plot to investigate the relationship between Television(hours) and Overweight (KG). Briefly explain the selection of each variable on the X and Y axes and why? Calculate and interpret the coefficient of correlation (r) between Television(hours) and Overweight (KG).…

Four Quarters the Same as $1? In a study of the “denomination effect,” 43 college students were each given one dollar in the form of four quarters, while 46 other college students were each given one dollar in the form of a dollar bill. All of the students were then given two choices: (1) keep the money; (2) spend the money on gum. The results are given in the accompanying table (based on “The Denomination Effect,” by Priya Raghubir and Joydeep Srivastava, Journal of Consumer Research, Vol. 36.) Use a 0.05 significance level to test the claim that whether students purchased gum or kept the money is independent of whether they were given four quarters or a $1 bill. Is there a “denomination effect”?

You may need to use the appropriate appendix table or technology to answer this question. Sparr Investments, Inc., specializes in tax-deferred investment opportunities for its clients. Recently Sparr offered a payroll deduction investment program for the employees of a particular company. Sparr estimates that the employees are currently averaging $100 or less per month in tax-deferred investments. A sample of 39 employees will be used to test Sparr's hypothesis about the current level of investment activity among the population of employees. Assume the employee monthly tax-deferred investment amounts have a population standard deviation of $75 and that a 0.05 level of significance will be used in the hypothesis test. (a) What is the type II error in this situation? O Reject Sparr Investments' claim that the employees are currently averaging $100 or less per month in tax-deferred investments when it is true. O Reject Sparr Investments' claim that the employees are currently averaging…
