Using the Hurricane data from the previous worksheets, support or refute this claim. Explain your answer using the statistical reasoning developed in the worksheets. (CI and p -values) Cat, 3-5 Hurricanes per decade Calculate the mean, mode, median and range. Then answer the questions below.

Compare your sample mean to the population mean. How does it compare? Is your sample mean representative of the population mean? Statistical analysis of the above data reveals a confidence interval of 1.10652102+/- the mean. What are the upper and lower confidence limits? Suppose 10 hurricanes were to occur this decade. Based on the 95%CI, what is the probability of such an occurrence? Based on statistical theory of the normal distribution, what conclusion can you draw
