Normal Distribution and Pic

2. Based on the scale of measurement for each variable listed below, which measure of central tendency is most appropriate for describing the data?

2. I have 20% chance to have cavity gene. If I do have the gene, there is 51% chance that I will have at least one cavity over 1 year. If I don’t have the gene, there is 19% chance that I will have at least one cavity over 1 year. Given that I have a cavity in 6 months, what’s the probability that I have at least a cavity over 1 year?

Beverly and Kyle Nelson currently insure their cars with separate companies paying $450 and $375 a year. If they insure both cars with the same company, they would save 10 percent on the annual premiums. What would be the future value of the annual savings over ten years based on an annual interest rate of 6 percent?

5. Give the standard deviation for the mean and median column. Compare these and be sure to identify which has the least variability?

2. Compute the means for the following set of scores saved as Ch. 2 Data Set 3 using IBM® SPSS® software. Print out a copy of the output. (Please refer to attachment)

If John gets an 90 on a physics test where the mean is 85 and the standard deviation is 3, where does he stand in relation to his classmates? (he is in the top 5%, he is in the top 10%, he is in the bottom 5%, or bottom 1%)

Therefor there is a probability that the cards drawn will equal a sum of 10.

There are 2 baskets. 1 basket has 1 white ball; 2 green balls; and 2 red balls. The other basket has 3 yellow balls; 1 blue ball; 1 green ball; and 1 brown ball. You pick 1 ball from the first basket and 1 ball from the other basket. What is the probability

1. If Mrs. Beach wanted to invest a lump sum of money today to have $100,000 when she retired at 65 (she is 40 years old today) how much of a deposit would she have to make if the interest rate on the C.D. was 5%?

Example: Patrick flipped a number cube 40 times. A 5 appeared 10 times. The experimental probability of rolling a 5 is 10 out of 40 or 25%

b. What is the probability of failing on the first 2 trials and passing on the
