Refer to Table 1. (i) Construct a frequency and relative frequency table using a class interval of 5, starting at -0.5. (ii) Construct a histogram. (iii) Construct a frequency polygon. (iv) Construct a cumulative frequency and relative cu- mulative frequency table. What is the probability that a price-earnings ration drawn at random from the sample will fall between 4.5 and 14.5? (v) Construct a cumulative frequency polygon. Problem 2. The mean and median of the data in Table 1 are = 10 Median = 9 Use the grouped frequency table from Prob. 1 (i) to cal- culate the mean and median for the grouped data Problem 3. The standard deviation of the data in Table 1 is 8 = 5.41 Use the grouped frequency table from Prob. 1 (i) to cal- culate the standard deviation for the grouped data
