Question I practice. 1. A sample of 50 listeners of Light and Easy radio station was taken and the data on their ages was organised into a frequency distribution. Number of listeners Age 13 - 20 4 21-28 8 29-36 10 37-44 12 45 - 52 9 53-60 7 a. Construct a frequency table with columns for class midpoint, frequency, relative frequency, cumulative frequency, and cumulative relative frequency. b. Draw a histogram for the above distribution. C. Based on the table above, calculate the following: i. Minimum ii. Maximum iii. Mode iv. Mean V. Median vi. First Quartile vii. Third Quartile viii. Interquartile Range ix. Amplitude x. Mean Absolute Deviation xi. Variance xii. Standard Deviation d. Draw a scatter plot of the data to see the underlying trend in the relationship between age and number of listeners. e. Perform Pearson Correlation analysis for the above data. f. Discuss about the insight derived from (1) to (5). JL
