Use the normal distribution to find a confidence interval for a proportion p given the relevant sample results. Give the best point estimate for p , the margin of error, and the confidence interval. Assume the results come from a random sample. A 95% confidence interval for the proportion of the population in Category A given that 18% of a sample of 450 are in Category A. Round your answer for the point estimate to two decimal places, and your...

1. A company that produces brendis concerned about the distribution of the amount of sodium in its bread. The company takes a simple random sample of 100 slices of bread and compute the sample mean to be 103 milligrams of sodium per slice. Assume that the population standard deviation is 10 milligrams a) Construct a 95% confidence interval estimate for the mean sedium level. b) Construct a 99% confidence intervalestime for the mean sodium level. 2. Fill...

(COMPUTE AND INTERPRET CONFIDENCE INTERVAL ESTIMATES) A college admissions officer sampled 120 entering freshmen and found that 42 of them scored more than 550 on the math SAT. Construct a 99% confidence interval for the proportion of all entering freshmen at this college who scored more than 550 on the math SAT. Find the critical values, find E , the margin of error, then compute and interpret your interval estimate with a full sentence. Critical value: (draw, label & shade)...
