American Medical Association wants to estimate the proportion of medical doctors who had a solo practice. How many doctors should be included in the study if the association wants 99% confident that the estimate is within 5 percentage point of the true population proportion?

The number of doctors 'n' = 6.76

Step-by-step explanation:

Explanation:-

Given Estimate of the true population proportion = 5 % = 0.05

Given level of significance ∝ = 99% or 1%

Z₀.₀₁ = 2.576

The margin of error is determined by

we know that

Cross multiplication , we get

√n = 0.2576≅0.26

squaring on both sides,we get

n = 0.0676 X 100

n=  6.76

Final -

The number of doctors 'n' = 6.76

step-by-step explanation:

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
