1) How many ways are there to arrange 2 basil plants, 3 thyme plants,
and 5 rosemary plants in a line on a windowsill, if we don't distinguish between plants of the same type?
2) Two trucks leave a warehouse at the same time. One travels due north at an average speed of 58
58 miles per hour, and the other travels due south at an average speed of 46
46 miles per hour. After how many hours will the two trucks be 208
208 miles apart?
3) Rejecting the null hypothesis that the population slope is equal to
zero or no relationship and concluding that the relationship between x and y is significant does not enable one to conclude that a cause-and-effect relationship is present between x and y. Explain why.
