This table show the population of owls in a park in different years. the quadratic regression equation that models these data's is y=-1.34^2+10.75x-11.3 . x values represent year : 1,2,3,4,5,6 y values represent number of owls : 0,2,7,14,9,4 using this model the predicted number of owls in year 9 is about -23. does this prediction make sense ? why or why not? a: yes, because the owl population is endangered . b: no, because the owls went to live somewhere else. c: yes, because that is the result of substituting x=9 d: no, because you can't have a negative number of owls.

It appears that people who are mildly obese are less active than leaner people. one study looked at the average number of minutes per day that people spend standing or walking. among mildly obese people, the mean number of minutes of daily activity (standing or walking) is approximately normally distributed with mean 376 minutes and standard deviation 64 minutes. the mean number of minutes of daily activity for lean people is approximately normally distributed with mean 528 minutes and standard deviation 107 minutes. a researcher records the minutes of activity for an srs of 7 mildly obese people and an srs of 7 lean people. use z-scores rounded to two decimal places to answer the following: what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 420 minutes? what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 lean people exceeds 420 minutes?
