Answer:
39
Step-by-step explanation:
let the missing value be x,
We note that the number of data values= 10
Sum of all data values,
= 26+35+10+18+15+37+25+20+15+x
= (201 + x)
We are given that the mean is 24
Recall that,
mean = sum of data values ÷ number of data values
substituting the known values from above,
24 = (201 + x) ÷ 10 (multiply both sides by 10)
(24)(10) = (201 + x)
240 = 201 + x (subtract 201 from both sides and rearrange)
x = 240 - 201
x = 39
Hope this helps!
