Suppose you want to estimate the proportion of traditional
college students on your campus who own their own car. From
research on other college campuses, you believe the proportion
will be near 30%.What sample size is needed if you wish to be 98%
confident that your estimate is within 0.02 of the true
proportion?

Current Attempt in Progress Suppose you want to estimate the proportion of cars that are sport utility vehicles (SUVs) being driven in Kansas City, Missouri, at rush hour by standing on the corner of 1-70 and 1-470 and counting SUVs. You believe the figure is no higher than 0.40. If you want the error of the confidence interval to be no greater than 03, how many cars should you randomly sample? Use a 90% level of confidence. Appendix A Statistical...

Suppose you want to estimate the proportion of traditional college students on your campus who own their own car. You have no preconceived idea of what that proportion might be. What sample size is needed if you wish to be 98 % confident that your estimate is within 0.05 of the true proportion? A sample size of nothing is needed. (Round up to the nearest whole number.)

Suppose you want to estimate the proportion of traditional college students on your campus who own their own car. From research on other college campuses, you believe the proportion will be near 25%. What sample size is needed if you wish to be 99% confident that your estimate is within 0.02 of the true proportion? A sample size of is needed. (Doudun to the noroet whole number

You want to obtain a sample to estimate a population proportion. Based on previous evidence, you believe the population proportion is approximately p 0.35. You would like to be 96% confident that your esimate is within 2% of the true population proportion. How large of a sample size is required? Hint: Shouldn't the answer be a WHOLE NUMBER n=2390.171

You want to estimate the proportion of students at OSU who use Instagram. You select a random sample of 150 OSU students and find that 47% use Instagram. If you want to construct a 95% confidence interval, what will the margin of error be? As you calculate this, attempt to round along the way to three decimal places as you are engaging in your calculations in order to make the computations easier. Choose the answer option that is closest to...

You live near Mac Donnel's and want to estimate the proportion ,p, of your neighbors who go there on a typical day. a. How many people in your neighbors should include in your random sampling to be 97% sure that you are within 7% of p? b. If 21 out of 25 of Ashley's neighbors visit Mac Donnel's every day, how many people should include in your random sampling to be 86% sure that you are within 3% of p?...

Suppose you want to estimate a particular population proportion p of “success”, say the proportion of Cal Poly students who plan to go to Coachella this year. Consider two methods of collecting data. 1) Select a simple random sample of size n for a fixed, specified n. Let X be the count of successes in the sample. For example, select a sample of n = 30 students, and say for the selected sample X = 3 students plan to attend...

Due Sun 05/31/2010 11:59 pm You want to obtain a sample to estimate a population proportion. At this point in time, you have to be for the population proportion. You would like to be 99.9% confident that you esimate is within 0.25 population proportion. How large of a sample size is required? Hint: Shouldn't the answer be a WHOLE NUMBER Do not round mid-calculation. However, use a critical value accurate to three decimal places Points possible: 1 Unlimited attempts. Score...

5) You now need to estimate with 90% confidence the population proportion of the amounts of financial aid that are at least $10,000. You randomly sample the population of financial aid awards that you are studying. You then record whether the amount of the award is at least $10,000. The results of that sampling process are shown in appendix two below. Using this information, construct the required confidence interval and explain its meaning. Appendix Two: (Award is at least $10,000?)...
