Constructing Frequency, Cumulative Frequency, and Relative Frequency Tables 1. Identify the class width, class midpoints, and class boundaries for the given frequency distribution. Then compute the cumulative and relative frequency. Daily Low Frequency Cumulative Relative Temperature (F°) Frequency Frequency 40-42 1 43-45 3 46-48 5 49-51 11 52-54 7 55-57 7 58-60 1 a) Draw a histogram for the above table. Make sure to label clearly the lower and upper bounds of each class. b) Do the data values represent a normal distribution? Why?

Calculating Sample Statistics 2. Listed are head injury measurements from small cars that were tested in crashes. The measurements are in "hic," which is a measurement of a standard "head injury criterion," (lower "hic" values correspond to safer cars). Find the mean, variance, standard deviation, median, range, midrange, mode and coefficient of variation for the data. Round decimals to two places. Car A В C D E F "hic" 520 302 547 391 367 360 529 Mean Variance Standard Deviation Median Range Midrange Mode Coefficient of Variation The Normal Distribution, Standard Values and Probabilities 3. With a height of 65 inches, Ronald was the shortest president of a particular club in the past century. The club presidents of the past century have a mean height of 66.6 inches and a standard deviation of 2.4 inch. a) Compute the z score for Ronald's height. Round decimal to three places. b) Is Ronald's height usual or unusual? Explain. c) Use the club data to find the probability that the next club president will have a height taller than 69 inches.
