It costs you $10 to draw a sample of sizen=1 and measure the attribute of interest. You have a budget of $2,500. Complete parts aand b below......a. Do you have sufficient funds to estimate the population mean for the attribute of interest with a 95% confidence interval 4 units inwidth? Assume o = 16.Select the correct choice below and fill in the answer box to complete your choice.Yes, because the required sample size isNo, because the required sample size isb. If you used a 90% confidence level, would your answer to part a change? Explain.A. Yes, because the total cost decreases and the funds are now sufficient.B. No, because the total cost decreases and the funds are still sufficient.C. Yes, because the total cost now exceeds the budget.D. No, because the total cost still exceeds the budget.

In statistics, a confidence interval is a range of possible values for an unknown parameter. The interval has an associated confidence level. A 95% confidence level is most common, but other levels, such as 90% or 99%, are sometimes used.

In a study of government financial aid for college students, it becomes necessary to estimate the percentage of full-time college students who earn a bachelor's degree in four years or less. Find the sample size needed to estimate that percentage. Use a 0.03 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 = (Round up to the nearest integer.) b. Assume prior studies have shown that about 55% of full-time students earn bachelor's degrees in four years or less. n=D (Round up to the nearest integer.)
Zoologists investigated the reproductive traits of spider mites with an infection. Male and female pairs of infected spider mites were mated in a laboratory and the number of eggs produced by each female recorded. Summary statistics for several samples are provided in the accompanying table. Assume that the sampled populations are approximately normal. Complete parts a and b. Click the icon to view the table. a. For each type of female-male pair, construct a 90% confidence interval for the population mean number of eggs produced by the female spider mite. The 90% confidence interval for both untreated pairs is (, ). (Round to the nearest hundredth as needed.) - X The 90% confidence interval for male treated pairs is Data table (Round to the nearest hundredth as needed.)

In a study of government financial aid for college students, it becomes necessary to estimate the percentage of full-time college students who earn a bachelor's degree in four years or less. Find the sample size needed to estimate that percentage. Use a 0.02 margin of error and use confidence level of 95%. Complete parts (a) through (c) below. a. Assume that nothing is known about the percentage to be estimated. (Round up to the nearest integer.) b. Assume prior studies have shown that about 40% of full-time students earn bachelor's degrees in four years or less. (Round up to the nearest integer.) c. Does the added knowledge in part (b) have much of an effect on the sample size? O A. No, using the additional survey information from part (b) only slightly reduces the sample size. OB. Yes, using the additional survey information from part (b) dramatically reduces the sample size. OC. Yes, using the additional survey information from part (b) only slightly increases the sample size. OD.…
Your state is considering raising the legal age for consumption of alcoholic beverages to 21 years old. How large a sample size must be taken to make an estimate of the true proportion of citizens who favor this move? The error should be no more than 0.01 with 99% confidence. Select one: a. 16641 b. 167 c. 1670 d. 6450 e. 65
Cora wants to determine a 90% confidence interval for the true proportion of high school students in the area who attend their home basketball games. How large of a sample must she have to get a margin of error less than 0.02? Assume we have no prior estimate of the proportion and want a conservative choice for the sample size.

You plan to conduct a survey to find what proportion of the workforce has two or more jobs. You decide on the 90% confidence level and a margin of error of 2%. A pilot survey reveals that 5 of the 44 sampled hold two or more jobs. (Use t Distribution Table & z Distribution Table.) How many in the workforce should be interviewed to meet your requirements? (Round z-score to 2 decimal places. Round up your answer to the next whole number.)
