Answer 1

χ in it. ... The mode of the following data is 36. ... CLASS, 0-10, 10- 20, 20-30, 30-40, 40-50, 50-60, 60-70 ... 120− 6x=160−10x ... Get Instant Solutions, 24x7.

Modal class = 30 - 40 So, f0 = x, f1 = 16, f2 = 12, l = 30 and h = 10 Mode = l + f1 - f02f1 - f0 - f2 × h 36 = 30 + 16 - x2 × 16 - x - 12 × 10 6 = 16 ...
