Question

A data of 10 observations has a minimum value of 15 and a maximum value if 25. What is the mean value

Answer 1

Answer:

mean = 19.5

This could be the answer with assumptions considered in question below

Step-by-step explanation:

As question is incomplete but considering value starting with 15 in a series as x,x+1,x+2........ and last value 24 i.e tenth value.

then mean of observations= (15+16+17+18+19+20+21+22+23+24)/10

mean = 19.5

This could be the answer with above assumptions
