Answer:
1.66
Explanation:
The mean of a set of data is 4.68 and its standard deviation is 2.83. Find the z score for a value of 9.38
Given that :
Mean (m) = 4.68
Standard deviation (s) = 2.83
Value of x = 9.38
Zscore = (x - mean) / standard deviation
Zscore = (9.38 - 4.68) / 2.83
Zscore = 4.7 / 2.83
Zscore = 1.6607773
Hence, Zscore for a value of 9.38 is 1.66
