A political candidate has asked you to conduct a poll to determine what percentage of people support her. If the candidate only wants a 1% margin of error at a 99% confidence level, what size of sample is needed

16589.44

Step-by-step explanation:

z score for 99% confidence interval = 2.576

Margin of error = 1% = 0.01

Formula =

Margin of error = z score × p(1 - p)/n

0.01=2.576 × √ (0.25)/n

0.01=2.576 × 0.5/√ (n)

Crops Multiply

0.01× √ (n) = 2.576 × 0.5

divide both sides by 0.01

√(n) = 2.576 × 0.5/ 0.01

√n =128.8

Square bother sides

n = 128.8²

n = 16589.44

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.
