In a regression analysis, a nurse researcher found a correlation of .82 between pain relief scores and satisfaction with nursing care. She also calculated the following for her regression analysis:
Pain Relief (x): Mean = 58 sd = 3.9
Satisfaction (y): Mean = 42 sd = 4.4
slope = 1.56
y intercept = - 3.53
1. What will be the predicted satisfaction score (expressed as a point estimate) for a patient with a pain relief score of 62?
2. What is the standard error of estimate when predicting satisfaction from knowledge of pain relief score?
3. What would be the interval estimate for satisfaction for the patient in problem 1?
The natural rate of capacity utilization is defined as the rate at which Y is zero. What is this rate for the period under the study?
What concepts and constructs would you use to study this phenomenon? How might the concepts or constructs relate to explanatory hypotheses? Explain.
A random sample of n=9 men between 30-39 years old is asked to do as many sit ups as they can in one minute. The mean number is x=26.2 and the standard deviation is s=6. Find a 95% confidence interval for the population mean.
Find a 90% confidence interval for the population mean salary of such personnel. What is the margin of error.
A random sample of 24 patients found a standard deviation of 520. Assume the variable is normally distributed and = 0.01. What are the critical values?
Ran parts and found 1% defective(1 out of 100). Made a change to the process and want to rerun parts. How many parts do we need to check (and find 0% defective) for a 90% confidence factor
The probability that student pilot passes the written test for a private pilot's license is 0.7. Find the probability that the student will pass the test: (a) on the third attempt (b) before the fourth attempt.
Also include information about the number of participants you would assess and how you would go about estimating effect size and statistical power (when relevant).
Use an ANOVA with α=.05 to determine whether there are any significant differences among the three treatment means. (both by hand and in PASW), for the hand version of problem.
What is the rejection point at α = .10 and indicate if you would accept or reject H o ?
