A)

You are performing a twotailed teat with teat statistic z = 0.19, find the pvalue to 4 decimal place5 |:| You want to obtain a sample to estimate a population proportion. Based on previous evidence, you believe the population proportion is approximately 63%. You would like to be 90% confident that your esimate is within 2.5% of the true population proportion. How large of a sample size is required? (Do not round mid-calculation, with the exception of the critical value being rounded to three decimal places.) 17 =You are performing a right-tailed test with test statistic = = 0.1, find the p-value to 4 decimal placesYou are performing a twotailed t teat with teat statistic t = 0.49 and a sample of Size 4'], nd the p-value to 4 decimal places |:| If n=560 and p (p-hat) =0.41, find the margin of error at a 99% confidence level Give your answer to three decimalsAssume 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 235 with 48.9% successes at a confidence level of 98%. M.E. = % 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 placeIf n = 120 and p (p-hat) = 0.65, construct a 90% confidence interval. Give your answers to three decimals
