Julia wants to estimate the percentage of people who submit their tax returns online. she surveys 330 individuals and finds that 65 submit their tax returns online. find the margin of error for the confidence interval for the population proportion with a 95% confidence level.

 0.0432

Step-by-step explanation:

Formula of Margin of Error :-

Given : Sample size : n= 400

The proportion of individuals use public transportation.=

Level of confidence = 0.95

Significance level :

Critical value :

Substitute the values in the given formula , we get

Hence, the margin of error for the confidence interval for the population proportion with a 95% confidence level. = 0.0432

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
