The correlation between cash bonuses paid by a company to its executives (Y) and the annual pay of executives (X) is 0.735. The standard deviation in cash bonuses is $15,618 and the standard deviation in annual pay is $28,077. The estimated slope of best fitting line relating x and y is?
Please explain how you arrive at the answer.
Using this information, calculate Blpha risk (probability of Type II error) if the true population mean really is 79.
When combining probabilities, to find the probability of one event AND another event, the separate probabilities should be:
what is the probability that the sample mean of IQ scores will not differ from the population mean by more than 2 points? (Round your answer to four decimal places.)
The point estimate for the difference between the proportions is:
You have been asked to study the effects of an employee-wide training program, in a company of 500 employees, designed to reduce the amount of customer complaints.
Why is cumulative relative frequency distribution so much more informative that just relative frequency distribution? Use examples to explain these differences.
Set up the null and alternative hypotheses, and perform the hypothesis test with a significance level of 0.05.
Compute test statistic and p -value for each sample. (Negative amount must be pointed out by minus sign.)
Conduct a hypothesis test to determine if the average cardiac outputs measured by the two evaluators differ. Use a significance level of 0.02.
At a board meeting of 20 businessmen, all of whom wear ties, what is the probability that:
Give a possible description why serum cholesterol values for older males are lower than for younger males and reverse is true for females.
Test whether there is a statistical difference between the two proportions at the 5% significance level.
