Given data
Sample size n = 284
No. of students work full time is P = 55 % = 0.55
No. of students who not work full time is Q = 100- 55 % = 45 % = 0.45
The standard deviation is given by
Put all the values in above equation we get
S.D. = 8.38
This is the standard deviation for the number of students who work full time.
