Answer:
X is a binomial random variable
Then the condition is met
Step-by-step explanation:
Sample size n₁ = 400
X represents the number of brand-name lightbulbs)
P(X) = 44/400
P(X) = 0,11
X is a binomial random variable it only could be either no defective or defective ( only two conditions or values).
To make use of the condition of approximation of binomial distribution to a normal distribution it is required that the products:
p*n = 0,11*400 = 44 and q = 1 - 0,11 q = 0,89
q*n = 0,89 * 400 = 356
both p*n q*n are greater than 5.
Then the condition is met
