Alpha Corporation receives a shipment of flour every morning from their supplier. The flour is in 40 kg bags and Alpha will reject any shipment that is more than 4% underweight. The foreman samples 60 bags with each shipment and the bags average more than 4% underweight, the whole shipment is returned to the supplier. Determine the value for the standard error of the proportion

Answer:

Given that,

Proportion (p) = 0.04

Sample size (n) = 60

To find standard error of the proportion (SEp)

= sqr(0.04(1-0.04)/60)

= 0.025298

~ 0.0253

    Suppose a huge internet-based lighting company receives a shipment of several thousand boxes of light bulbs every Tuesday. Inspectors return the merchandise to the manufacturer if the proportion of damaged light bulbs is more than 0.06 (6%). Rather than inspect all of the packages, 100 boxes are randomly sampled. As long as at least 10 damaged and 10 undamaged light bulbs are found, a one-sample 2-test is run with a significance level of 0.01 to see if the proportion of...
