STAT A researcher is interested in how affectionate pet owners are. She found that the general population distribution is skewed to the right, the mean degree of affection is 82.9, and the standard deviation is 14.78. She was then interested in finding out whether cat owners are less affectionate than other pet owners. She samples a group of 100 cat owners and finds that their mean is 54.8. What is the standard deviation of the comparison distribution

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
