Suppose that scores on a particular test are normally distributed with a mean of 110 and a standard deviation of 20. What is the
qaws [65]

Answer:

The minimum score needed to be in the top 2% of the scores on the test

is  n = 10,00,000

Step-by-step explanation:

<u><em>Step(i)</em></u>:-

Mean of the Population = 110

Standard deviation of the Population = 20

The estimated error = 2% = 0.02

<u><em>Step(ii)</em></u>:-

The estimated error is determined by

                        E = \frac{S.D}{\sqrt{n} }

                       0.02 = \frac{20}{\sqrt{n} }

               ⇒ \sqrt{n} = \frac{20}{0.02} = 1000

Squaring on both sides, we get

                   n = 10,00,000

The minimum score needed to be in the top 2% of the scores on the test

is  n = 10,00,000

kvv77 [185]

Answer:

12 wooden rulers

23 plastic rulers

Step-by-step explanation:

Total rulers sold - 35

Total profit - $82

1 wooden ruler - $3

1 plastic ruler - $2

$3 x 12 = $36

$2 x 23 = $46

$46 + $36 = $82

12 + 23 = 35 rulers
