The blue catfish (Ictalurus Furcatus) is the largest species of North American catfish. The current world record stands at 143 pounds, which was caught in the John H. Kerr Reservoir (Bugg's Island Lake) located in Virginia. According to American Expedition, the average weight of a blue catfish is between 20 to 40 pounds. Given that the largest blue catfish ever caught was at the John H. Kerr Reservoir, you believe that the mean weight of the fish in this reservoir is greater than 40 pounds. Use the data below, which represents the summary statistics for 42 blue catfish caught at this reservoir, and a 0.05 significance level to test the claim that the mean weight of the fish in the John H. Kerr Reservoir is greater than 40 pounds. n=42;  ¯x=40.63 pounds;  s=3.49 pounds a) Identify the null and alternative hypotheses?H0:               H1: c) Identify the appropriate significance level.d) Calculate your test statistic. Write the result below, and be sure to round your final answer to two…

The table pertains to scheduled commercial carriers. Fatalities data include those on the ground except for the September 11, 2001, terrorist attacks. Use this information given in the table. For fatalities the mean an = 66.7 the median = 14.5 and the mode = 2 2. The year 2001 was clearly an anomaly. If the data for that year is reduced by 239 fatalities, which of the three measures change and what are their new values for each of the following? please help:(
