Step 1
The problem asks us to find the minimum sample size \( N \) required so that the population proportion \( \widehat{p} \) is estimated within a margin of error of 0.0015 at a 97% confidence level. Show more…

A) A population proportion is estimated to be 0.0283 < p < 0.0333 at 96 % confidence level. Using 4 decimal places for z_c, find the least sample size required to ensure this estimate. B) A population proportion is estimated to be within 0.0025 of p̂ = 0.3822 at 94 % confidence level. Using 4 decimal places for z_c, find the least sample size required to ensure this estimate.

Calculate the confidence interval to estimate the population proportion for each of the following. a. $98 \%$ confidence level; $n=450 ; \hat{p}=0.10$ b. $95 \%$ confidence level; $n=240 ; \hat{p}=0.01$. c. $\alpha=0.04 ; n=265 ; \hat{p}=0.50$
If n = 310 and X = 248, construct a 95% confidence interval for the population proportion, p. Give your answers to three decimals < p <
