You draw two cards from a standard deck of 52 cards, but before you draw the second card, you put the first one back and reshuffle the deck.
a. Are the outcomes on the two cards independent? Why?
b. Find P (3 on 1st card and 10 on 2nd)
c. Find P (10 on 1st card and 3 on 2nd)
d. Find the probability of drawing a 10 and a 3 in either order.
Based on the scatter diagram, does there appear to be any relationship between the number of assemblers and production? Explain.
The simple coefficient of determination is the proportion of total variation explained by the regression line.
Run a multiple regression and interpret all the findings, R 2 , F, IV coefficients, and the intercept. Then in paragraph format, identify and report the following:
What is the probability that a respondent said neither the Big Ten nor the Pac-10 would have a team in the Rose Bowl?
Start rolling dice until a particular number, say 3, is obtained, and keep track of how many rolls are necessary. Repeat 100 times. Then find the average.
how many individuals will I need to sample if I want a 95% margin of error to be no more than 3%, I want to know if the results are significant at = 10%. With the information given.
The data in the scatterplot below are an individual's weight and the time it takes (in seconds) on a treadmill to raise his or her pulse rate to 140 beats per minute. The o's correspond to females and the +'s to males.
We are interested in comparing the proportions of males and females who think earning a large salary is very important to them. I surveyed 200 of each gender and recorded their answers to the question as yes or no.
Environmental Protection Agency (EPA) fuel economy estimates for automobile models tested recently predicted a mean of 24.80 mpg and a standard deviation of 6.2mpg for highway driving. Assume that a normal model can be applied.
where p is the binomial probability of returning a completed survey, and log is the natural logarithm. The multiple logistic regression output from fitting this model is given below.
Create a 90% confidence interval for proportion of all kernels that would not pop.
