Explanation Given data: The given values are shown Table 1. Table 1 Time that it takes a person to assemble the part (minutes) Frequency 4 15 5 20 6 28 7 34 8 28 9 24 10 16 The total number of people, n = 165 . Formula used: From equation 19.7 in the textbook, the formula to find mean for any sample is, x ¯ = ∑ ( x f ) n (1) Here, x ¯ is the mean, x is the time taken by the people, f is the frequency, n is the total number of people. From equation 19.8 in the textbook, the formula to find standard deviation is, s = ∑ ( x − x ¯ ) 2 f n − 1 (2) Calculation: Draw the histogram of time taken by the people for their respective frequency ( f ) value in Excel sheet by selecting the two columns of time and frequency and go to insert and click “column” bar chart and select “2-D column” bar chart, then the graph will be plotted as shown in Figure 1. The calculation of terms in equation (1) is shown in Table 2. Table 2 Time ( x ) Frequency ( f ) x f 4 15 60 5 20 100 6 28 168 7 34 238 8 28 224 9 24 216 10 16 160 The sum of all the terms x f is, ∑ x f = 60 + 100 + 168 + 238 + 224 + 216 + 160 ∑ x f = 1166 Substitute 1166 for ∑ x f , and 165 for n in equation (1) to find x ¯ , x ¯ = 1166 165 = 7
