Question 13 > Private nonprofit four-year colleges charge, on average, $27,599 per year in tuition and fees. The standard deviation is $6,748. Assume the distribution is normal. Let X be the cost for a randomly selected college. a. What is the distribution of X? X - N( b. Find the probability that a randomly selected Private nonprofit four-year college will cost less than 26,207 per year. (Round to 4 decimal places.) c. Find the 70th percentile for this distribution. $ (Round to the nearest dollar.)
Question 4. At a busy shopping mall on Saturdays, the length of time it takes to find a parking space at 11 A.M. follows a normal distribution with a mean of five minutes and a standard deviation of two minutes. Find the probability that it takes seven minutes or more to find a parking space. What is the probability of finding a parking spot within one minute? How many minutes do the luckiest 25% of shoppers need to find a parking spot? How many minutes do the unluckiest 25% need to find a parking spot?

3.32. Shakespeare's plays. Figure 3.13 is a histogram of the lengths of words used in Shakespeare's plays. Because there are so many words in the plays, we use a histogram of percents. What is the overall shape of this distribution? What does this shape say about word lengths in Shakespeare? Do you expect other authors to have word length distributions of the same general shape? Why? 25 15 10 5 1 2 3 4 5 6 7 8 9 10 11 12 Number of letters in word FIGURE 3.13 Histogram of the lengths of words used in Shakespeare's plays, for Exercise 3.32. 20 Percent of Shakespeare's words

a. Use technology to produce a dotplot and b a histogram of this distribution. Try a few different histograms, with varying subintervals, to find the one that you consider the best summary of the distribution. b. Write a few sentences describing the shape, center, and spread of this distribution.
Which of these graphs show a normal distribution probability?
Question 2, a. & b
Would the data sets that follow possess relative frequency distributions that are symmetric, skewed to the right, or skewed to the left? a. The salaries of all persons employed by a large company Choose the correct answer below. A. The data set is symmetric because the mean value would be nearly the same as the median value. The measurements would be centered around a single value. B. The data set is skewed left because the mean value would be less than the median value. There would be a few, but small, measurements that would pull the mean away from the median toward the left. C. The data set is skewed right because the mean value would be more than the median value. There would be a few, but large, measurements that would pull the mean away from the median toward the right.
