QuestionEstimate $P($ fewer than 3$)$ using normal approximation when $np \geq 5$ and $nq \geq 5$ with $n=14$ and $p=0.4$. If not, state that normal approximation is not suitable.

Studdy Solution
Look up the value in the standard normal distribution table or calculate it using a calculator.
$$(Z < -.63) =0.0516$$So, the probability of fewer than3 successes is approximately0.0516.
