2-2.A study is being conducted in which a variable of interest has 1,000 observations. The minimum value in the data set is 300 points and the maximum is 2,900 points. Use the 2k = n guideline to determine the minimum number of classes to use in developing a grouped data frequency distribution. Based on the answer to part a, determine the class width that should be used (round up to the nearest 100 points). 2-19.The California Golf Association recently conducted a survey of its member. Among other questions, the members were asked to indicate the number of 18-holerounds that they played last year. Data for a sample of 294 members are provided in the data file called Golf Survey. Using the 2k = n guideline, what is the minimum number of classes that should be used to display these data in a grouped data frequency distribution? Referring to part a, what should the class width be, assuming you round the width up to the nearest integer? Referring to parts a and b, develop a grouped data frequency distribution for these golf data. Based on your answer to part c, construct and interpret a frequency histogram for the data. 2-22 .The manager of AJ’s Fitness Center, a full-service health and exercise club, recently conducted a survey was to determine the satisfaction level of his club’s customers.
