Find the margin of error M.E

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 319 with 20.1% successes at a confidence level of 90%. M.E.= 96 Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places. Round final answer to one decimal place

Assume that all grade-point averages are to be standardized on a scale between 0 and 4. How many grade-point averages must be obtained so that the sample mean is within 0.008 of the population mean? Assume that a 98% confidence level is desired. If using the range 4-0 =1. Does the sample size seem practical? range rule of thumb, o can be estimated as 4 The required sample size is (Round up to the nearest whole number as needed.) Does the sample size seem practical? O A. No, because the required sample size is a fairly large number. O B. No, because the required sample size is a fairly small number. OC. Yes, because the required sample size is a fairly small number. O D. Yes, because the required sample size is a fairly large number.

If n 180 and p (p-hat) =0.07, find the margin of error at a 95% confidence level. Round to 4 places. Z-scores may be rounded to 3 places or exact using technology.

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 354 with 96 successes at a confidence level of 80%. M.E. = % (report answer accurate to one decimal place; answer should be reported as a percent, not a decimal—though do not type the percent sign) Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.

Assume that all grade-point averages are to be standardized on a scale between 0 and 6. How many grade-point averages must be obtained so that the sample mean is within 0.01 of the population mean? Assume that a 99% confidence level is desired. If using the range rule of thumb, o can be estimated as 6- = 1.5. Does the sample size seem practical? range 4 4 The required sample size is (Round up to the nearest whole number as needed.)
