In 2003, there were many media reports about the number of shark
attacks in florida. at the end of the year, there were a total of 30
unprovoked shark attacks. by comparison, there were 246 shark attacks
over the prior ten years. using the pre-2003 data, simulate the number of shark attacks for 2003. based on your simulation, what is the probability that there would be 30 or more shark attacks in that year?

Arecent study focused on the number of times men and women who live alone buy take-out dinner in a month. assume that the distributions follow the normal probability distribution and the population standard deviations are equal. the information is summarized below. statistic men women sample mean 24.85 21.33 sample standard deviation 5.54 4.93 sample size 34 36 at the 0.01 significance level, is there a difference in the mean number of times men and women order take-out dinners in a month? state the decision rule for 0.01 significance level: h0: μmen= μwomen h1: μmen ≠ μwomen. (negative amounts should be indicated by a minus sign. round your answers to 3 decimal places.) compute the value of the test statistic. (round your answer to 3 decimal places.) what is your decision regarding the null hypothesis? what is the p-value? (round your answer to 3 decimal places.)
