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.
Answer:
Step-by-step explanation:
First find the surface area of the clyinder and find the area circles and subtract
Then find the surface area of a cone, remove the circle area and double it.
Clyinder surface area (without circle area) 2πrh+2πr2=2·π·4·6+2·π·42≈251.32741
251.32741 - 50.2 - 50.2
Cone area: A=πr(r+h2+r2)=π·4·(4+32+42)≈113.09734
113.09734 - 50.2 - 50.2
Total: 12.69734 + 150.92741 = 163.62475
