An article in Knee Surgery Sports Traumatology, Arthroscopy, "Effect of provider volume on resource utilization for surgicalprocedures," (2005, Vol. 13, pp. 273-279) showed a mean time of 116 minutes and a standard deviation of 18 minutes forACL reconstruction surgery for high-volume hospitals (with more than 300 such surgeries per year). If a high-volume hospitalneeds to schedule 10 surgeries, what is the mean and variance of the total time to complete these surgeries? Assume thetimes of the surgeries are independent and normally distributed.Mean = iVariance = iminutesminutes²

Studies by the U.S. Dept. of Education have shown that when full-time undergraduate students work at a part-time job more than 15 hours/week, their grades suffer and time to graduation is extended. If the NCSU financial aid office wants to estimate the mean hours worked per week by NCSU undergrads to within .5 hour with 95% confidence, how many students should they sample? Assume the range of hours worked per week is 10 to 22 hours.
Nationally, the amount of debt from college student loans is exceeded only by mortgage debt and is a significant burden for many students after graduation. This photo shows the average student loan debt for a recent graduate of 4-year public colleges and universities in each state and Washington D.C. The distribution of the data can be approximated by a normal model with mean u = $28045 and standard deviation = $3604. a) a high school guidance counselor who provides college attendance advice to seniors wants to know the highest 10% of average student loan debt values. Use the normal model to determine the cutoff value for the highest 10% of average student loan debt value.
Is there any difference in the variability in golf scores for players on a women's professional golf tour and players on a men's professional golf tour? A sample of 20 tournament scores from events in a tour for women showed a standard deviation of 2.4683 strokes, and a sample of 30 tournament scores from events in a tour for men showed a standard deviation of 2.2117. Conduct a hypothesis test for equal population variances to determine if there is any statistically significant difference in the variability of golf scores for male and female professional golfers. Use α = 0.10. A. State the null and alternative hypotheses. 1.H0: σ12 ≤ σ22 Ha: σ12 > σ22 2. H0: σ12 = σ22 Ha: σ12 ≠ σ22 3. H0: σ12 > σ22 Ha: σ12 ≤ σ22 4. H0: σ12 ≠ σ22 Ha: σ12 = σ22 B.

An organizational psychologist conducted a study to see whether upgrading a company's older computer system to newly released, faster machines would cause an increase in productivity from the current average of 120 units with a standard deviation of 20. The new system will be tested in a single department with 45 employees. The company has decided that an increase of fewer than 10 units will not justify purchasing the new system. What is the predicted effect size for an increase of 10 productivity points (130 units)? Show your work

Researchers interested in determining the relative effectiveness of two different drug treatments on people with a chronic illness established two independent test groups. The first group consisted of 14 people with the illness, and the second group consisted of 12 people with the illness. The first group received treatment 1 and had a mean time until remission of 172 days with a standard deviation of 8 days. The second group received treatment 2 and had a mean time until remission of 183 days with a standard deviation of 5 days. Assume that the populations of times until remission for each of the two treatments are normally distributed with equal variance. Construct a 95% confidence interval for the difference u, -H, between the mean number of days before remission after treatment 1 (u,) and the mean number of days before remission after treatment 2 (u). Then find the lower limit and upper limit of the 95% confidence interval. Carry your intermediate computations to at least three…
Given that the researcher wants to be sure the mean difference in the change in hemoglobin levels has a margin of error no more than 0.2 g/dL and the difference in the stand deviation between the mean hemoglobin levels for the two forms of iron supplements used to treat anemia is 1.2 g/dL, what is the desired number of recruits for the study, assuming the individuals will participate in a crossover trial, if the study’s attrition rate is expected to be .25? Group of answer choices n = 139 n = 554 n = 185 n = 55,320

Medical researchers interested in determining the relative effectiveness of two different drug treatments on people with a chronic mental illness established two independent test groups. The first group consisted of 10 people with the illness, and the second group consisted of 14 people with the illness. The first group received treatment 1 and had a mean time until remission of 185 days, with a standard deviation of 5 days. The second group received treatment 2 and had a mean time until remission of 179 days, with a standard deviation of 8 days. Assume that the populations of times until remission for each of the two treatments are normally distributed with equal variance. Can we conclude, at the 0.05 level of significance, that the mean number of days before remission after treatment 1, μ1 , is greater than the mean number of days before remission after treatment 2, μ2 ? Perform a one-tailed test. Then fill in the table below. Carry your intermediate…
