When asked, "Do kids regularly carry weapons in your school?" 14,252 students said yes, and 115,336 students said no. With a 95% level of confidence, find the margin of error (MOE) associated with the sample proportions. (Give the answer to one decimal place, if needed.) MOE =  %

Use the sample data and confidence level given below.   A research institute poll asked respondents if they felt vulnerable to identity theft. In the​ poll, n=979 and x=530 who said​ "yes." Use a 95% confidence level.   Find the best point estimate of the population proportion p, q, p, q, e, n

Construct a confidence interval for the population proportion p. n ? 144, x ? 86, 90% confidence

In a random sample of 68 people,17 are classified as​ "successful."   a. Determine the sample​ proportion, p, of​ "successful" people. b. If the population proportion is 0.70​,determine the standard error of the proportion.

An instructor wanted to know if his students are better at math or writing. He had students take both a math and then a writing test and he compared the results using SPSS. He found the following results: ( look at graphs )  a. What test was done?b. Report results in APA style.

A survey asked, "How important is it to you to buy products that are made in America?" of the 600 Americans surveyed, 450 responded, "It is important." For each of the following levels of confidence, find the sample proportion and the margin of error (MOE) associated with the poll. (Give the answers to one decimal place, if needed.)
