Problem # 1 Assuming that the heights of college women are normally distributed with a mean of 66 inches and a standard deviation of 2.5 inches, answer the questions below. 1A. Draw the normal curve to represent this data. Label the mean and the standard deviations along the top of the curve. Be sure to include a line along the bottom. Shade in the area that represents the probability that an acre will be between 58.5 inches and 68.5 inches. 1B. 1C. 1D. What percentage of these women are taller than 68.5 inches? What percentage of these women are shorter than 61 inches? 1B. 1C. What is the probability that one of these women will be taller than 63.5 inches? 1D.

Think of your own example of a data set that would follow a normal distribution and explain why.

Psychology students at a university completed the Dental Anxiety Scale questionnaire. Scores on the scale range from 0 (no anxiety) to 20 (extreme anxiety). The mean score was 11 and the standard deviation was 3.5. Assume that the distribution of all scores on the Dental Anxiety Scale is normal with u = 11 and o = 3.5. Complete parts a through c. Click here to view a table of areas under the standardized normal curve. a. Suppose you score a 18 on the Dental Anxiety Scale. Find the z-value for this score. z= 2 (Round to the nearest hundredth as needed.) b. Find the probability that someone scores between 10 and 15 on the Dental Anxiety Scale. P(10sxs 15) = (Round to four decimal places as needed.) c. Find the probability that someone scores above 17 on the Dental Anxiety Scale. P(x> 17) =| (Round to four decimal places as needed.)

Assume the birth weights at a local hospital have a normal distribution with a mean of 110 oz and a standard deviation of 15 oz. Draw a normal curve and label the mean and each value which is one, two, or three standard deviations above the mean.  Then label each value which is one, two, or three standard deviations below the mean.

Sketch a standard normal curve and shade the area that lies to the left of a. 2.15, b. - 1.61, c. 0, and d. - 7. Then determine the area under the standard normal curve that lies in the area of interest for each part. Click here to view page 1 of the normal distribution table.
