find the sample size needed to estimate the percentage of democrats who have tattoos. Use a 0.05 margin of error. use a confidence level of 99%, and use results from prior harris poll suggesting that 15% of democrats have tattoos.

A manufacturer of sprinkler systems used for fire protection in office buildings claims that the true average system-activation temperature is 130 . A sample of n=9 systems, when tested, yields a sample average activation temperature of 131.08 F with a standard deviation 1.5F. Suppose the distribution of activation times is normally distributed. Is there sufficient evidence to believe that the average activation temperature of the sprinklers is different from manufacturer claims? (Use 5% significance level)? If you calculate a 95% confidence interval, will 130 be inside or outside the interval? Explain your answer without calculating the interval.
A large automobile insurance company selected samples of single and married male policyholdersand recorded the number who made an insurance claim over the preceding three yearperiod. Single Policyholders Married Policyholders n1 # 400 n2 # 900Number making claims # 76 Number making claims # 90 a. Use α # .05. Test to determine whether the claim rates differ between single and marriedmale policyholders.b. Provide a 95% confidence interval for the difference between the proportions for thetwo populations.
The EPA considers indoor radon levels above 4 picocuries per liter (pCi/L) of air to be high enough to warrant amelioration efforts. Tests in a sample of 200 Centre County Pennsylvania homes found 127 of these sampled households to have indoor radon levels above 4 pCi/L. Using a 96% confidence level estimate the proportion of all Centre County Pennsylvania homes having the indoor radon level above 4pCi/L. Finally give a confidence statement.
Pottery Archaeologists can use the chemical composi-tion of clay found in pottery artifacts to determine whether different sites were populated by the sameancient people. They collected five samples of Romano–British pottery from each of two sites in Great Britainand measured the percentage of aluminum oxide in each.Based on these data, do you think the same people usedthese two kiln sites? Base your conclusion on a 95%confidence interval for the difference in aluminum oxidecontent of pottery made at the sites. (A. Tubb, A. J. Parker,and G.

A random sample of 64 bicycle-riding adults in Portland indicated that 24 always wore a helmet while riding. A random sample of 80 bicycle-riding adults in Amsterdam indicated that 18 always rode a helmet while riding. Answer: A. Use the sample information to develop a 90% confidence level interval estimate for the difference between the proportions of bicycle-riding adults that wear a helmet in two cities. B. Based on the sample results, can you conclude that the population proportion of bicycle-riding adults in Portland who always wear a helmet is greater than the population proportion of bicycle-riding adults in Amsterdam who always wear a helmet? Use a 0.05 level of significance to conduct the test
A manufacturing plant manager defines production as out of control when the overall rate of defects exceeds 4%. A random sample of 150 items results in 9 defects. Use a 95% confidence level to test the claim that production is out of control.
As part of the National Health and Nutrition Examination Survey, the Department of Health and Human Services obtained self-reported heights and measured heights for males aged 12 – 16. All measurements are in inches. Using a 0.05 significance level, is there sufficient evidence to support the claim that there is a difference between self-reported heights and measured heights of males aged 12 – 16? Also be sure to include the confidence interval. What does this suggest about the average difference between self-reported and actual heights? Write an APA-style results section for what you find. Reported: 68 71 63 70 71 60 65 64 54 63 66 72 Measured: 67.9 69.9 64.9 68.3 70.3 60.6 64.5 67 55.6 74.2 65 70.8
The state education commission wants to estimate the proportion of tenth-grade students that have reading skills at or below the eighth-grade level. How large a sample would be required to estimate the proportion of tenth graders reading at or below the eighth-grade level using 90% confidence level with a margin of error of 0.05 if: a)p = 0.10 from an earlier study b)no estimate of p is available
(c) Rashid carried out pyrolysis of sawdust in a semi-batch reactor and obtained replicates of measurement under the same conditions in order to test the precision of the method. The recorded values for biochar are 22.23, 22.18, 22.25, 22.09, and 22.17 wt%. Using a suitable test, analyze whether the value of 22.09 wt% is a valid measurement at a 95% confidence level?
A group of medical students volunteering at a maternity hospital in Florida are looking to determine the proportion of newborns born at a healthy weight. They conduct a study of 650 newborns and find that 392 were born at a healthy weight. What is the point estimate for the true proportion? What is Maximal Margin of Error (E) at 90% confidence? Construct a 90% confidence interval for the true proportion of interest.
