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

Hey guys i need help finding m&lt;1 PLEASE HELPPP
valentinak56 [21]

Step-by-step explanation:

You see the 90 degree angle marking at the top left so that angle is 90 degrees. However, it is bisected into two so both sections of that 90 degree angle equal 45. One triangle is equal to 180 degrees, so the triangle at the tops' missing angle is 52. I don't know if you heard of vertical angles but that angle opposite 83, because it is a vertical angle, is also 83 degrees. This is as far as I've gotten. Not sure how to solve the rest without more information
