Lifetimes of weather stations on mars (continued) if the true standard deviation of weather station lifetimes is 120 martian days, what is the probability the sample standard deviation is 136 days or more? what sampling distribution should we use to compute this probability?

David estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x. create a question you could ask that could be answered only by graphing or using a logarithm.
