His/her lowered score was most likely due to statistical regression.

<h3>How to determine the reason?</h3>

The missing options in the question are:

D.  Testing E.  Statistical regression

From the question, we have:

  • September = 99th percentile
  • February = 90th percentile

A change (whether higher or lower) in the score is caused by statistical regression.

This is so because several variables could attribute to the change in the score.

The relationship between these variables is referred to as statistical regression

A firm buys components from two suppliers: 60 percent from supplier A and the rest from supplier B. It so happens that 9 percent
Llana [10]

Answer:

0.114,0.5263

Step-by-step explanation:

Given that a firm buys  components from two suppliers:

A : 60%  Defective 9%

B:40%  Defective 15%

a) the probability that the next component the firm buys is defective

=prob purchased from A and defective + prob purchased from B and defective

= 0.60(0.09)+0.40(0.15)\\= 0.054+0.06\\=0.114

b)  the probability that the component that the firm buys is from supplier B if we know that it is defective

=Prob from B and defective/Prob defective

= \frac{0.40(0.15)}{0.114} \\=0.5263
