You may need to use the appropriate appendix table or technology to answer this question. A simple random sample of 400 individuals provides 132 Yes responses. (3) What is the point estimate of the proportion of the population that would provide Yes responses? |:| (b) What is your estimate of the standard error of the proportion, 05? (Round your answer to four decimal places.) (c) Compute the 95% condence interval for the population proportion. (Round your answers to four decimal places.) | |t| You may need to use the appropriate appendix table or technology to answer this question. In a survey, the planning value for the population proportion is p* = 0.35. How large a sample should be taken to provide a 95% condence interval with a margin of error of 0.05? (Round your answer up to nearest whole number.) :1 You may need to use the appropriate appendix table or technology to answer this question. At 95% confidence, how large a sample should be taken to obtain a margin of error of 0.05 for the estimation of a population proportion? Assume that past data are not available for developing a planning value for p*. (Round your answer up to the nearest whole number.) :1 You may need to use the appropriate appendix table or technology to answer this question. The following sample data for the weight of two homemade chocolate chip cookies (in ounces) are from a normal population: 13, 11, 15, 18, 16, 14, 9, 8. (a) What is the point estimate of the population mean? X (b) What is the point estimate of the population standard deviation? (Round your answer to three decimal places.) X (c) With 95% condence, what is the margin of error for the estimation of the population mean? (Round your answer to one decimal place.) X (d) What is the 95% confidence interval for the population mean? (Round your answer to one decimal place.) lx tol Ix (e) W1ich are correct interpretations of the 95% confidence interval for the population mean, in the context of the problem? (Select all that apply.) We are 95% confident that the true mean weight of two homemade chocolate chip cookies is between the values listed in part (d). There is a 0.95 probability that the true mean weight of two homemade chocolate chip cookies is between the values listed in part (d). I: I: I: We are 95% confident that the mean weight of the sample of eight sets of two homemade chocolate chip cookies is between the values listed in part (d). I: If 100 samples of eight sets of cookies are taken, and a 95% confidence interval is determined for the true average weight using each set of sample data, about 95 of the 100 confidence intervals will contain the true mean weight of two homemade chocolate chip cookies.
