1) A doctor claims that less than 75% of the patients that he performs a knee replacement surgery on return to work in the first 3 months after the operation. A sample of 50 patients that had a knee replaced by the doctor showed that only 34 of them returned to work within 3 months of the surgery. Test the doctor's claim at the 0.05 level ofsignificance. 2) A researcher wants to determine what proportion of all high school students plans to attend community college upon graduating. He has no idea of what the sample proportion will be. How large of a sample is required in order to be 90% sure that the sample proportion is off by no more than 2%? 3) A random sample of 42 C05 students contained 9 that owned an iPhone. A random sample of 116 Fresno State students contained 39 that owned an iPhone. Use these data to test the claim that the proportion of C05 students who own an iPhone is the same as the proportion of Fresno State students who own an iPhone at the 0.05 level of significance
