Q1) Assume that you are interested in studying determinants of use of plea-bargaining by state prosecutors. In a one-month period, you record for each state in US, the number plea-bargains per 1,000 cases (y) and average number of cases per prosecutor (x). Your hypothesis is that average number of cases per prosecutor may describe some of variation in use of plea bargaining across states. After gathering your data, you get the following statistics:
Sy = 12,507
Sx = 12,224
Sy2 = 4,578,619
Sx2 = 5,639,821
Sxy = 4,234,185
[N = 50].
a) Determine the value of b? Interpret.
b) What is the value of (a). What is the regression equation?
c) Using above regression equation, predict value of Y (number of plea bargains per 1,000) if the average number of cases per prosecutor is 150.
d) Calculate the correlation coefficient.
e) What is the coefficient of determination from these sample statistics? What does this coefficient indicate?
Find probability using normal distribution.Using N (1152, 84), the Normal model for weight of Angus steers, what percent of steers weigh.
Where should the warranty limits be set so that only 10 percent of the HDTVs need repairs at the manufacturer's expense?
Compute the median number of dependents?
Use Bayes's rule to find the conditional probability that Julianne is a carrier, given that she and Jason have one child who does not have cystic fibrosis.
An ANOVA procedure is used for data that was obtained from four sample groups each comprised of five observations. The degrees of freedom for the critical value of F are:
Find the expected GPA when SAT = 800. Find E (GPA|SAT = 1,400). Comment on the difference.
Such things as historical documents, newspaper reports, TV and radio broadcasts, when used in research, represents
Shows a sample mean of 1,261 with a standard deviation of 59. Should Pennsylvania adopt the new system for all toll roads in the state?
The critical value of F at 95% confidence when there is a sample size of 21 for the sample with the smaller variance, and there is a sample size of 9 for the sample with the larger sample variance is:
What percentage of the averages or medians of the sample will be greater than 140 seconds?
Does this sample indicate a smaller average? Use α = 0.05 and assume a normally distributed population.
Determine the mean and standard deviation of the data. What percentage of the data lies within one standard deviation of the mean value?
