Answer:
The sample required is
Step-by-step explanation:
From the question we are told that
The standard deviation is
The margin of error is
Given that the confidence level is 99% then the level of significance is mathematically evaluated as
Next we will obtain the critical value from the normal distribution table(reference math dot armstrong dot edu) , the value is
The sample size is mathematically represented as
substituting values
Since this equation is already in standard form, there is no need to convert it. Standard form is Ax + By = C. In this equation, 7 = A, 3 = B, and 10 = C. From standard form, Ax + By = C equals negative A over B.
7x + 3y = 10
↓
Then you'd simplify.
The slope cannot be simplified any more, so this would be the final answer.
