Question 2 A bank examiner's record shows that the probability of an error in a statement for a checking account at Trust Us Bank is 0.03. The bank statements are sent monthly. What is the probability that exactly two of the next 12 monthly statements for our account will be in error? Now use the cumulative probability option to find the probability that at most two of the next 12 statements contain errors. Use this result with subtraction to find the probability that more than two of the next 12 statements contain errors. Your Answer: X-B(0.03,12) P(x-12) P(x-12)3D0 P(error)= P3D0.03 n=12 X= no statement of error Search or type URL 4

5. Which of the following is NOT a characteristic of the normal probability distribution? The random variable assumes a value within plus or minus three standard deviations of its mean 99.72% of the time. The total area under the curve is always equal to 1. The graph of the curve is the shape of a rectangle. The mean is equal to the median, which is also equal to the mode.
1. A house painter found that it takes 40 minutes on average to paint a roof. Given a standard deviation of this task is 5 minutes and the times for roof painting is normally distributed, what is the probability that on any given day it will take the painter 50 minutes or more to paint a house roof? 2. Which of the following would you not use the normal distribution to approximate the binomial distribution? A. n = 100, p = 0.22 B. n = 100, p = 0.31 C. n = 100, p = 0.1 D. n = 100, p = 0.01 E. n = 100, p = 0.9
6.3.10 Question Help Three randomly selected households are surveyed. The numbers of people in the households are 2, 7, and 12. Assume that samples of size n 2 are randomly selected with replacement from the population of 2, 7, and 12. Construct a probability distribution table that describes the sampling distribution of the proportion of even numbers when samples of sizes n 2 are randomly selected. Does the mean of the sample proportions equal the proportion of even numbers in the population? Do the sample proportions target the value of the population proportion? Does the sample proportion make a good estimator of the population proportion? Listed below are the nine possible samples. 2,2 2,7 2,12 7,2 7,7 7,12 12,2 12,7 12,12 Construct the probability distribution table. Sample Proportion Probability Type an integer or fraction.)

3.37 In 2003, the average combined SAT score (math and verbal) for college-bound students in the United States was 1026. Suppose that approximately 45% of all high school graduates took this test and that 100 high school graduates are randomly selected from among all high school grads in the United States. Which of the following random variables has a distribution that can be approximated by a binomial distribution? Whenever possible, give the values for n and p. a The number of students who took the SAT b The scores of the 100 students in the sample c The number of students in the sample who scored above average on the SAT d The amount of time required by each student to complete the SAT e The number of female high school grads in the sample
Ch6. "A carpet manufacturing company is comparing the tensile strengths of two different types of synthetic fiber. Synthetic fiber A used in manufacturing carpet has tensile strength that is normally distributed with mean 75 psi and standard deviation 12 psi, and synthetic fiber B has tensile strength that is 70 psi and standard deviation 12 psi. Random sample of nA = 16 and nB = 9 of fiber specimens are selected. Find the probability that the sample mean of fiber specimen A exceeds the sample mean of fiber specimen B by 4."
