In order to invert a function, switch y and x in the definition, and solve for y again:
Solving for y, we have
This is a case of binomial probability, with n = 29, p = 0.11 and x = 5.
Using the function binompdf on my Texas Instruments calculator, as follows:
binompdf(29,0.11,5) = 0.117 (answer)
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
⇒
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
