A state-by-state survey found that the proportions of adults who are smokers in state A and state B were 21.3% and 26.9%, respectively. (Suppose the number of respondents from each state was2000.) At alphaαequals=0.01, can you support the claim that the proportion of adults who are smokers is lower in state A than in state B? Assume the random samples are independent. Find the critical value(s) and identify the rejectionregion(s). Find the standardized test statistic

Decide whether to reject or fail to reject the null hypothesis.

The surface area of the triangular prism is .

Gravel is being dumped from a conveyor belt at a rate of 25 ft3/min, and its coarseness is such that it forms a pile in the shape of a cone whose base diameter and height are always equal. how fast is the height of the pile increasing when the pile is 14 ft high? (round your answer to two decimal places.) ft/min

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.
