The local pilots association examined records from this year's census of its members. Ivanna is a member, and the census shows that she has 3105 hours ofFlight experience. After the census, the association found that its members had a mean of 4575 hours of flight experience with a standard deviation of 692hours.(a) Find the -score of Ivanna's flight experience relative to the flight exper ences of all the members of the pilotsassociation. Round your answer to two decimal places.(b) Fill in the blanks to Interpret the -score of Ivanna's flight experience. Make sure to express your answer in terms of apositive number of standard deviations.Ivanna's flight experience is standard deviations (Choose one) the mean flight experience of all themembers of the pllots association.abovebelow

Colleges announce an "average" SAT score for their entering freshmen. Usually the college would like this "average" to be as high as possible. A NewYork Times article noted, "Private colleges that buy lots of top students with merit scholarships prefer the mean, while open-enrollment public instituions like medians." Use what you know about the behavior of means and medians to explain these differences.
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.
