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 A researcher believes that the 60% rate is no longer valid and that the proportion should be higher. To see if this proportion is still valid, he surveys 100 women, 70 of whom say they have annual mammograms. If =0.05, calculate the followings: the sample proportion __%, margin of error __, confidence interval __, P-value__ (Rounding to 3^rddecimal place).
