The mode of the following frequency distribution is 38. Find the value of x.
∵ Mode = 38. ∴ The modal class is 30-40. Mode = \(l+\frac{f_1-f_0}{2f_1-f_0-f_2}\times h\) = 30 + \(\frac{16-12}{32-12-x}\) x 10 = 38 \(\frac{4}{20-x}\) x 10 = 8 8 (20 - x) = 40 20 - x = 5 X =...

In the following data, find the values of p and q. Also, find the median class and modal class.
Here, = 11 + 12 = 23 And 33 + q = 46 ⇒ q = 46 − 33 = 13 Thus, p is 23 and q is 13. Now, Here the maximum class frequency is 20, and the...
