If the probability of selecting a black chip and a white chip is 15/56, and the probability of selecting a black chip on the first draw is 3/8, find the probability of selecting the white chip on the second draw, given that the first chip selected was a black chip.

A random sample of local cat owners revealed that 10 randomly selected owners spent an average of $205 with standard deviation, s=26 dollars. Is there a significant statistical difference at 1% level of significance? To test the hypothesis, what would be your null and alternative hypotheses? a.
