A sample of 81 account balances of a credit company showed an average balance of $1,200 with a sample standard deviation of $126. You want to determine if the mean of all account balances is significantly different from $1,250. Use a .05 level of significance.
Using the original data, test at the 5% significance level that the population standard deviation of studying times is greater than 4 hours.
In a regression analysis, the sum of the squared deviations between y and y-bar is SST = 200.0. If the sum of the squared deviations about the regression line is SSE + 40.0, what is the coefficient of determination?
If the population standard deviation is s = 10, is the sample sufficient to demonstrate a significant effect? Again, assume a two-tailed test with a = 0.05.
A year ago, Air Force implemented new test for finding which candidates are most probable to become successful pilots. Now they wish to see if implementing pilot predictor test was a good idea. Scores have been standardized to facilitate comparis..
A manufacturer of executive jet aircraft is concerned with its profit picture over the short run. It produces two different models of planes, x1 and x2. Its profits are $30,000 for each x1 and $20,000 for each x2. There are two major constraints o..
Find out the probability distribution of blood types by gender in the group of 1000 individuals.The table below gives the distribution of blood types by gender in a group of 1000 individuals.
I tossed a coin 6 times and recorded the outcomes - H for heads and T for tails. The first set of tosses yielded HTHTTH and the second set of tosses yielded TTTHHH. Which set of tosses is more probable to happen? And why?
When is a regression equation used? What terms describe the fit of a regression equation to the data? What is the importance of the coefficient of determination (r2)?
Determine the standard error of students that favoured the move.
How many individuals will it need to sample to achieve this level of accuracy and confidence?
If Weight 1 is the weight (in pounds) of a random sample of five men who were accepted as models, and Weight 2 is the weight (in pounds) of a random sample of five men who were rejected as models, which of the following is the appropriate inferenc..
