Keith_Richards [23]

Her sister invited 22 guests. What you have to do to solve this problem is subtract 41-19. We have to do this because Rayliegh invited 19 more people than her sister, but invited a total of 41 people herself. So, to figure out how many people her sister invited we have to know that Rayliegh invited 19 more people and we have to subtract that from the total number she invited to get how many people her sister invited: 22 guests. Can you make me brainliest?

You want to obtain a sample to estimate a population proportion. At this point in time, you have no reasonable estimate for the
Vedmedyk [2.9K]

Answer:

416025

Step-by-step explanation:

For confidence interval of 99%, the range is (0.005, 0.995). Using a z-table, the z-score for 0.995 is 2.58.

Margin of error = 0.2% = 0.002.

Proportion is unknown. So, worse case proportion is 50%. p = 50% = 0.5.

\\ n = \left(\frac{\texttt{z-score}}{\texttt{margin of error}} \right )^2\cdot p\cdot (1-p) \\ = \left(\frac{2.58}{0.002} \right )^2\cdot 0.5\cdot (1-0.5)=416025

So, sample size required is 416025.
