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 range is the set of y.
(-4, 4) → 4
(-3, 0) → 0
(-2, 1) → 1
(-1, 3) → 3
(0, 0) → 0
(1, 5) → 5
Answer: {0, 1, 3, 4, 5}
Answer: B
Step-by-step explanation: 3/8 + 1/16 = 0.4375 and 7/16 = 0.4375
The product of 4xy and y² + 2x can also be written as
4xy(y² + 2x)
When we have brackets like this, we multiply whatever is left of the brackets by everything inside.
1) 4xy multiplied by y²
4xy x y² = 4xy³
2) 4xy multiplied by 2x
4xy x 2x = 8x²y
3) Add together 4xy³ and 8x²y
4xy³ + 8x²y
Radius is 11cm
diameter is 22cm
