In a study of government financial aid for college students, it becomes necessary to estimate the percentage of full-time college students who ear a bachelor's degree in four years or less. Find the sample size needed to estimate that percentage. Use a 0.01 margin of error and use a confidence level of 90%. Complete parts (a) through (c) below. a. Assume that nothing is known about the percentage to be estimated. n= 6,766 (Round up to the nearest integer.) b. Assume prior studies have shown that about 45% of full-time students earn bachelor's degrees in four years or less. (Round up to the nearest integer.)
7.1.36-T 34.31%, 5.83 of 17 pts A programmer plans to develop a new software system. In planning for the operating system that he will use, he needs to estimate the percentage of computers that use a new operating system. How many computers must be surveyed in order to be 99% confident that his estimate is in error by no more than four percentage points? Complete parts (a) through (c) below.

We are collecting data on the patients that have been vaccinated for the coronavirus, and the initial data shows a 90% success. We want the margin of error to be no more than 3%. We want to be extremely careful, so we are going to use a 99% confidence. Determine the smallest size of the sample to achieve this level of confidence. a 560 b 680 c 664 d 600 e 686

What sample size is needed to give a margin of error within+3% in estimating a population proportion with 90% confidence? We estimate that the population proportion is about 0.25. Round your answer up to the nearest integer. Sample size = i
The level of dissolved oxygen in a river is an important indicator of the water’s ability to support aquatic life. A research project is started to determine if the oxygen levels in the river have changed. It is known from a study done 10 years prior, that the mean oxygen levels in milligrams per liter for the river was 4.3. a- Write appropriate hypotheses for this test b- You collect water samples at 15 randomly chosen locations along the river and measure the dissolved oxygen. Here are your results in milligrams per liter: 4.53 5.5 4.01 5.04 4.83 4.66 3.29 4.4 2.87 5.23 5.42 5.73 4.13 6.38 5.55 Construct and interpret a 95% confidence interval for the mean dissolved oxygen level for this stream. c- Using the sample from part b, conduct a significance test of these results using a 5% significance level. Give complete results of the test including a p-value and an interpretation of the test results that someone not in this class could understand
You are given the smaple mean and the population m standard deviation. Use this info to construct the 90% and 95% confidence intervals for the population mean. Interpert the results and compare the widths of the confidence intervals. A random sample of 50 home theater systems has a mean price of $145. Assume the population standard deviation is $17.30
Find the indicated margin of error.In a survey of 6700 T.V. viewers, 3350 said they watch network news programs. Find the margin of error for the 99% confidence interval used to estimate the population proportion. a 0.0120 b 0.0158 c 0.0138 d 0.00900
