A simple random sample of size n=40 is drawn from a population. The sample mean is found to be x=121.2 and the sample standard deviation is found to be s=12.2. Construct a 99% confidence interval for the population mean. The lower bound is nothing . (Round to two decimal places as needed.)

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.

Divide. –40 ÷ –5 a –8 b 200 c -200 d 8
