(b) Calculate the mean value of the data. (c) Find the equation for the normal distribution that would fit the data as closely as possible. (d) Plot the normal distribution curve that is described by this equation. 1.11 Tabulate the relative frequencies for the following data and represent them graphically. X 15 16 17 18 19 20 21 22 23 24 1 4 7 12 13 9 6 4 3 1.12 Find the standard deviation of the following set of measurements: 15, 21, 19, 20, 18, 17, 22, 23, 16, 25. 1.13 Find the standard deviation of the set of measurements that occur with the frequencies tabulated below: 1 2 13 4 5 6 7 8 9 10 15 21 19 20 18 17 22 23 16 25 X 11 12 14 9 6 19 5 3 1.14 (a) Calculate the standard deviation o of the distribution consisting of the integers 1 to 5 inclusive. (b) Samples are taken of these integers, with each sample consisting of three different integers (10 samples in all) and a second distribution is formed from the means of these samples. If s is the standard deviation of this second distribution, prove that So = 1V6
