SOLUTION:

From given data,

A population has mean 33 and standard deviation 10 . What is the data value that has a z-score of 1 ? Write only a number as your answer.

mean ==33

standard deviation = =10

z-score = 1

We know that,

Z = (X-) /

By substituting the values

1 = (X-33) / 10 then,

X = (1*10 ) +33

X = 10 +33

X = 43

43 is the data value that has a z-score of 1
