The following is the most appropriate method for investigating the sociologist’s belief is,
A. A one-sample zz-test for a difference in population proportions
Step-by-step explanation:
- The young adults in a county get their news from online sources are 75 percent.
- But according to sociologist the percentage is actually greater than 75 percent.
- The correct answer is A one-sample zz-test for a difference in population proportions.
- The One proportion Z-test is used to compare proportion which is observed to a theoretical one, only when there are only two categories.
- A z-test is a statistical test which is used to determine whether there are two population which means there are different when the variances are known and the sample size is relatively large.
The formula for slope intercept form is y=mx+b where x is the slope and b is the y intercept. To find the slope you would have to do -2-7 over 8-0 and that would give you -9/8. That would be your slope. And I think you should be given a graph I’m not sure but if there is look at it and see what point you see on the y axis
Answer:
y=2/-1+8
Step-by-step explanation:
- -4= (-4,0) -4=x1 0=y1, 8= (0,8) 0=x2 8=y2
- formula is, y2-y1/x2-x1
- 8-0/0-4=8/-4=4/-2= 2/-1
- 2/-1 is the slope or (m), use (-4,0) or (0,8) i used (0,8) because its easier.
- (0,8), 0=x1 8=y1
- formula is y-y1=m(x-x1)
- y-8=2/-1(x-0) ---->distribute
- y-8=2/-1x-0 --->get y alone
+8 +8
- so the answer is y=2/-1+8
