Answer:
<em>The answer is 5</em>
Step-by-step explanation:
<em>From the question given, we have to make reference to what we already know.</em>
<em>Recall that, for normality assumptions np and nq values need to be greater than or equal to 5.</em>
<em>Hence,</em>
<em>P = 0.6, where p = population proportion </em>
<em>q = 1 – p=</em>
<em>1 – 0.6 = 0.4</em>
<em>n = 13</em>
<em>thus,</em>
<em>np = 13 x 0.6 = 7.8 > 5</em>
<em>Therefore,</em>
<em>nq = 13 x 0.6 = 5.2 > 5</em>
