Assume Mayor A had 52% of the votes in 2016. The estimated proportion of the votes for Mayor A in current election is 57% using a sample of 400 registered voters. Answer the following questions. Calculate the test statistics and fill in its value below (3 decimal points). Calculate the critical value and fill in its value in question 2 (3 decimal points). Is there enough evidence to suggest that the Mayor A has stronger support in current election at 2% significance level (question 3).

the answer is b i just did that

step-by-step explanation:

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.
