confidence Intervals

1. Compute a Confidence Interval with given SE. A clinical trial testing a new drug found that of 188 individuals in the experimental group that 312 had a good outcome. This "p is a point estimate for all individuals in the population who will have good outcome if they are administered the new drug. What is the point estimate, "p? Round to 3 decimal places, If necessary The standard error of this experiment is 0.022. Compute a 99% confidence interval for all individuals in the population who will have a good outcome if they are administered the new drug Remember to calculate a confidence interval you utilize: point estimate + z*-standard error Confidence Level 2 1.65 You may want to use this table to find z* 95 / 1-96 Fill In the blanks_ 94 10 2:38 Resulting in a confidence interval of ( Keep the interval as a decimal rounded to 3 decimal spots, not a percent, Compute and interpret a Confidence Interval with given SE. 2. A student wants to get an estimate of the proportion of individuals at his company who are right- handed. He randomly samples 115 individuals and finds that 89 are right-handed. This 'p is a point estimate for all individuals in the company who are right-handed. What is the point estimate, "p? Round to 3 decimal places, if needed. The standard error of this experiment is 0.039. Compute a 90% confidence interval for all Individuals in the population who will right handed. Confidence Level 2. Remember to calculate a confidence interval you utilize: point estimate + z*.standard error 1.65 95 10 1. 96 2.33 You may want to use this table to find z* 2.5% Fill in the blanks Resulting in a confidence interval of ( Keep the interval as a decimal rounded to 3 decimal spots, not a percent. What is an appropriate interpretation of the confidence interval? There is a 90% probability that the interval computed above captures the population proportion of individuals at the company who are right-handed. We are 90% confident that the interval computed above contains the truc proportion of all individuals at the company who are right-handed. 90% of individuals at the company who are right-handed will fall between the interval computed above. "We are 90% confident that the interval computed above contains the true proportion of the 115 individuals at the company who are right-handed
