Question

The following observations have been arranged in ascending order.
If the median of the data is 63, find x.
29, 32, 48, 50, x, x + 2, 72, 75, 87, 91
Hence find the mean of the distribution.

Answer 1

Answer:

x=63 so the observations are 29,32,48,50,63,65,72,75,87,91

mean= sum of observations/ no. of observations

mean= (29+32+48+50+63+65+72+87+91)/10

= 537/10

= 53.7
