sp2606 [1]

Answer: 119

Step-by-step explanation:

Since the prior estimate of population proportion of defective handles (p) is unknown , so we take p= 0.5

Given : Margin of error : E=0.09

Critical value for 95% confidence interval : $z_{\alpha/2}=1.96$

Required sample size :-

$n=0.5(1-0.5)(\dfrac{z_{\alpha/2}}{E})^2\\\\=0.25(\dfrac{1.96}{0.09})^2\\\\=118.567901235\approx119$

Hence, the minimum sample size required = 119

i.e. 119 handles from the shipment should be inspected.

<em>Find points from table.</em>

Point (-1, -1)

Point (0, -5)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>. Rate of change and slope are identical.

Substitute [SF]: $m=\frac{-5+1}{0+1}$
Add: $m=\frac{-4}{1}$
Divide: $m=-4$
