1)In a simulation model with one random input variable, how many values for the random input variable will be produced/used in one simulation of 1000 trials?

2)Participants at the state fair were given eight rings to toss. The number x of rings tossed onto a stick can be approximated by the probability distribution in the table. Use the probability distribution to find the mean and variance of the probability distribution

3)The 3-year-survival rate for a certain group of cancer patients

is known to be 40%. What is the probability (to four decimal places) that in a group of 10 patients, more than 6 patients survive at least 3 years (note: 3-year-survival is a binary outcome, and "success" is defined as survival).

4) A statistical analysis of 1000 long-distance telephone calls made

from the headquarters of PTCL, indicated that the length of these calls is normally distributed with seconds and seconds. i.How many calls lasted less than 180 seconds? ii.What is the length of a particular call if all calls are shorter at one percentile?

5) Please select the correct answer for the following question1) a. regardless of the shape of the population.

For a sample size of 1, the sampling distribution of the mean is normally distributed:

b. only if the population values are larger than 30.

c. only if the population is normally distributed.

d. None of these choices.

6) It is true-men who participate in body contact sports score higher

on the TEST (osterone) test of aggression. This is an example of which type of validity?

7) Dewey defeats Truman", 1948 US election ...

8) In 1967 someone claimed that serum cholesterol levels for women were

normally distributed with a mean of 192.1 and a standard deviation of 51.3 mg/100 ml. What level separates the women with the top 30% of Serum cholesterol levels?

 

9) In a study that looked as the effect on car crash severity, researchers

found the average mean speed in fatal accidents was 42 miles per hour with a standard deviation of 15 miles per hour. Legislators are debating lowering the 65 mile per hour speed on highways based on the argument that the higher speed will result in more fatalities. What percentage of fatal accidents occur based on the researchers data at a speed of 65 or more miles per hour? What would you recommend?

10) You have a jar with 4 blue, 5 red, and 3 green marbles. You select 2 marbles from the jar. Find the probability you end up with
(a) at least 1 green marble
(b) one and only one green marble
(c) two marbles of the same color

11) sample data and confidence level given below to complete parts? (a) through? (d).In a study of cell phone use and brain hemispheric? dominance, an Internet survey was? e-mailed to 2581 subjects randomly selected from an online group involved with ears. 959 surveys were returned. Construct a 99?% confidence interval for the proportion of returned surveys.
