A study determined that 60% of women older than age 50 have annual mammograms. A researcher believes that the 60% rate is no longer valid and the proportion should be higher. To see if this proportion is still valid, he surveys 100 women, 75 of whom say they have annual mammograms. if a=0.05, caculate the sample proportion, confidence interval, margin of error, and p value.
