If Gabriel takes a 25 question multiple choice test and receives a score of 80%, how many questions did he answer correctly? 15 If his teacher used a 95% confidence interval to correctly estimate the true percentage of correct answers that he should have scored on this exam, what possible grades could the teacher reasonably assign to Gabriel? Anything from Numero to Numero However, because Gabriel's teacher must pick only one number to represent his grade, what percentage will the teacher typically assign as the grade? Numero The table below shows which hand is favored by each person from a sample of 100 people (50 male and 50 female). Use the information in the table to answer the following questions. Left-Handed Right-Handed Male 15 35 Female 10 40 Determine the probability that a randomly selected person from the sample will be female or left-handed. Numero % (Round to the nearest whole percentage) Compute a 95% confidence interval for the true proportion of the population that is left-handed. Numero % to Numero Compute a 95% confidence interval for the true proportion of the population that is right-handed. Numero % to Numero %
