An office of admission document claims that 54.2% of uva undergraduates are female. to test this claim, a random sample of 205 uva undergraduates was selected. in this sample, 56% were female. is there sufficient evidence to conclude that the document's claim is false? carry out a hypothesis test at a 2% significance level.

a. the value of the standardized test statistic:
b. the rejection region for the standardized test statistic:
c. the p-value is
d. your decision for the hypothesis test:

Ascientist places 24 cells in a petri dish. she knows the cells grow at an exponential rate, doubling in number every hour. how long will it take (in hours) for there to be 1100 cells in the dish? time to 1100 cells: 5.51832530 hours how long will it take to reach 110 cells? time to 110 cells : 2.1963972 hours what is the average rate of change in the number of cells between 9 hours and 11 hours? average rate of change: cells per hour what is the instantaneous rate of change after 7 hours? instantaneous rate of change: cells per hour note: you can earn partial credit on this problem.
