Homework Answers
Answer:-
Here student remembered that
when we don't have idea what the population proportion would be and
we have only margin of error and level of significance then we
should take proportion p as 0.5 , otherwise we can't go for further
calculation.

Thanks

We want to construct a 95% confidence interval for the true proportion of all adult males who have spent time in prison, with a margin of error of 0.02. From previous studies, we believe the proportion to be somewhere around 0.07. The required sample size is, therefore: Select one: a. 620 b. 626 c. 632 d. 670

A) A certain region would like to estimate the proportion of voters who intend to participate in upcoming elections. A pilot sample of 25 voters found that 17 of them intended to vote in the election. Determine the additional number of voters that need to be sampled to construct a 95% interval with a margin of error equal to 0.06 to estimate the proportion. The region should sample ____ additional voters. B) Determine the sample size needed to construct a...

a. Assume that a sample is used to estimate a population proportion p. Find the 95% confidence interval for a sample of size 198 with 42 successes. Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate to three decimal places. 95% C.I. = b. A political candidate has asked you to conduct a poll to determine what percentage of people support her. If the candidate only wants a 0.5% margin of error at a 99% confidence...

Hi. Please help with these 4 problems. I keep getting the incorrect answer and i dont know what I am doing wrong :( Thank you in advance. 1) You want to obtain a sample to estimate a population proportion. Based on previous evidence you believe the population proportion is approximately p= 0.31. You would like to be 90% confident that your estimate is within 2.5% of the true population proportion. How large of a sample size required. I got 932...
