An oncologist at the CDC would like to know if there has been a change in this percentage over the last two years. A random sample of 606 women (40 and older) is taken, and each is asked the Q 1 [7/7] date of their last mammogram. Q 2 [1/1] Q 3 [2/2] . Verify that the assumptions have been satisfied to conduct a hypothesis test. o Q 4 [2/2] o Random sample? |Select an answer v Q 5 (0/10) o The variable recorded was: Select an answer Q 6 (0/10) 0 np = and n(1 - p) = Both of the values are greater than 10: |Select an answer v Q 7 (0/10) + D Q 8 (0/13) It was found that 421 women in the sample had a mammogram in the last two years.
