please answer clearly
5. Suppose you pay $2.00 to roll a fair die with the understanding that you will get back $5.00 for rolling a 4 or a 2, nothing otherwise. What is the expected amount you win (or lose)? A) $-1.00 B) S-0.33 C) S-2.33 D) S-1.33 E) None of the Above 15. Use the given sample data: construct a 95% confidence interval for the population mean: n = 13, xbar = 14.2, s = 2.7 A) (11.91, 16.49)...

22. Use standardization ( scores) to determine which has a better relative position: a score of 75 on a statistics test with a mean of 60 and a standard deviation of 10 or a score of 36 on an accounting test with a mean of 30 and a variance of 16? A) Z-1.5 and Z - 375 so Statistics has best performance B) Z-1.5 and Z -1.5 both tests so the same performance C) Z-1.5 and ZA - 375 so...

Using simple regression, determine whether test scores are
significantly related to sales performance. Use significance level
of 0.05%. Clearly interpret the slope (beta coefficient) and the
adjusted R squared value you obtained.
Using multiple regression, determine whether test scores and
number of months are significantly related to sales performance.
Use significance level of 0.05%. Clearly interpret the slopes (beta
coefficients) and the adjusted R squared value you obtained.

Determine and plot the moment M which must be applied to the crank OA in order to hold the cylinder of mass m 9 kg in equilibrium. Neglect the effects of the mass of OA and friction and consider the range 0 0s 180°. After you have the plot evaluate M at 0 68° and 114°. State the maximum and minimum values of the absolute value of M and the values of e for which these extremes occur, and physically...

In order to determine whether or not a driver's education course improves the scores on a driving exam, a sample of 6 drivers were given the exam before and after taking the course. The results are shown below. Assume the population of differences is normally distributed. Let d = Score After - Score Before. Driver Score Before the Course Score After the Course 1 83 87 2 89 88 3 93 91 4 77 77 5 86 93 6 79...

A set of data (test scores), can be summarized by a frequency distribution chart. For example, if the list of test scores is: 90 85 100 50 50 85 60 70 55 55 80 95 70 60 95 80 100 75 70 95 90 90 70 95 50 65 85 95 100 65 then the frequency distribution chart looks like the one below: value frequency ------ ------------ 100 3 95 ...
