Answer:
a). 9 to 5
b). 5 to 14
Step-by-step explanation:
If there are 9 boys then there are 5 girls because 14 - 9 = 5.
So, there are 5 girls of 14 students in the class.
If a variable is binomially distributed with n trials and a success probability of p, then the mean = np, variance = np(1–p) and standard deviation = square root of variance.
In this case, n = 1200, p = 0.35. So, mean = (1200)(0.35) = 420,
variance = (1200)(0.35)(1–0.35) = 273,
standard deviation = square root of variance = √273 = 16.52.
