How do you find (b.), (c.), and (g.)??

(a) Compute a 95% CI for the mean age (in years). (Enter your answer using interval notation. Round your numerical values to two decimal places.) (32.94, 49.54) years (b) Compute a 95% CI for the mean white blood count (in thousands) (use the variable named "First WBC (x 1000) following admission") following admission. (Enter your answer using interval notation. Round your numerical values to two decimal places.) (6.18,8.94) x thousands (c) Compute a 90% CI for the mean white blood count (in thousands) (use the variable named "First WBC (x 1000) following admission") following admission. (Enter your answer using interval notation. Round your numerical values to two decimal places.) (6.42,8.70) x thousands (d) What is the relationship between your answers to (b) and (c)? The 90% confidence interval is wider than the 95% confidence interval since we are requiring more confidence. o The 90% confidence interval is narrower than the 95% confidence interval since we are requiring less confidence. The 90% confidence interval is narrower than the 95% confidence interval since we are requiring more confidence. The 90% confidence interval is wider than the 95% confidence interval since we are requiring less confidence. (e) What is the best point estimate of the percentage of males among patients discharged from Pennsylvania hospitals? 40 % (f) What is the standard error of the estimate of the percentage of males among patients discharged from Pennsylvania hospitals? (Round your answer to four decimal places.) 9.7980 % (g) Provide a 95% CI for the percentage of males among patients discharged from Pennsylvania hospitals. (Enter your answer using interval notation. Round your numerical values to two decimal places.) (20.80, 59.20) X %
