You determined that the distribution of annual salaries of NBA players is bell-shaped and symmetrical about the mean salary, do you think introducing Michael Jordan's last annual salary of more than $30 million would skew this distribution?
Craft one page brief of the statistical results (include any additional pages needed for any APA tables or graphs and the SPSS syntax and output) in which you do the following:
Jones Nissan in Sumter, South Carolina, sold 15 Nissans yesterday. What is the probability that exactly 0 vehicles require warranty service?
In drawing an inference using a single mean in hypothesis testing, you often have a choice between doing a z-test or a t-test. Many researchers will always choose to do the t-test even under circumstances where the z-test would work as well.
Suppose the people have weights that are normally distributed with a mean of 164lb and a standard deviation of 30lb. Find the probability?
How large should the sample size be if she wishes to be accurate within $0.10. A previous study showed that the standard deviation of the price was $.12.
The daily revenue totals for the next 30 days will be monitored. What is the probability that the mean daily revenue for the next 30 days will be between $7000 and $7500?
What is the probability that 19 from a sample of 22 shoppers will spend less than $20? What is the probability that at least 12 but not more than 17 from a sample of 22 shoppers will spend less than $20?
Would it be reasonable to conclude that the population mean is 63 pounds?
What is the difference between the Confidence Interval and the Prediction Interval given in a Minitab printout of a multiple regression? When do you use each?
In analyzing two independent small samples you notice that the standard deviation for both samples are the same. How does this affect the S2p (the pooled variance)? Explain your answer.
What is approximately the largest sample mean of another sample of n= 16 participants you would expect to obtain from this finite population?
There is a 0.05 probability of thunderstorms in a major U.S. city. If there is a thunderstorm in that city, the probability is 0.28 that a flight departing that major city will be late.
