An exam consists of 44 multiple-choice questions. Each question has a choice of five answers, only one of which is correct. For

Paladinen [302]

Answer:

0.3960

Step-by-step explanation:

X - no of questions answered correct is binomial since each question is independent of the other and there are two outcomes

p = Prob of any one question right = 0.2 (1/5)

n = 44

Normal approximation would be mean = np = 8.8 and Variance = npq = 7.04

Std dev = $\sqrt{7.04} \\=2.65335$

X is N(8.8,2.6534)

Or Z = $\frac{x-8.8}{2.6534}$

Since we approximate discrete to continuous continuity correction is to be applied

$x\geq 10$ means x≥9.5

P(X≥9.5) = 0.3960
