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...

Determine the sample size needed to construct a 99% confidence interval to estimate the average GPA for the student population at a college with a margin of error equal to 0.4. Assume the standard deviation of the GPA for the student population is 3.0. The sample size needed is (Round up to the nearest integer.)
a. Assume that a sample is used to estimate a population proportion p. Find the margin of error M.E. that corresponds to a sample of size 343 with 292 successes at a confidence level of 99.8%. M.E.= b. You measure 46 textbooks' weights and find they have a mean weight of 79 ounces. Assume the population standard deviation is 7.5 ounces. Based on this, construct a 90% confidence interval for the true population mean textbook weight. Give your answers as...
