researchers wish to test the effect of living environment on cholesterol level they take a sample of people from a rural area and a sample of people from an urban area and compare their cholesterol levels. what would be the best statistical test for them to utilize? group of answer choices two-sample t-test anova linear regression chi-square

Answers

To test the effect of living environment on cholesterol levels using samples from rural and urban areas, the best statistical test to utilize would be the two-sample t-test.

The two-sample t-test is appropriate in this case because it compares the means of two independent groups (rural and urban residents) to determine if there is a significant difference between their cholesterol levels.

This test will help researchers determine if living environment has an impact on cholesterol levels.

Given: 5x + 3 > 4x + 7. Choose the graph of the solution set.

Answers

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$5x+3 > 4x+7$

solve for x

Group terms that contain the same variable, and move the constant to the opposite side of the inequality

$5x-4x > 7-3$

$x> 4$

The solution is the interval-------> (4,∞)

All real numbers greater than $4$

The solution is the shaded area to the right of the vertical dashed line

see the attached figure

Let's solve your inequality step-by-step.

5x+3>4x+7

Step 1: Subtract 4x from both sides.

5x+3−4x>4x+7−4x

x+3>7

Step 2: Subtract 3 from both sides.

x+3−3>7−3

x>4

Answer:

x>4
