a claim frequently made by college academic advisors is that more than 73% of freshmen intramural participants do well enough academically to be retained to the next school year (that is, they do not flunk out). to evaluate this claim use the data in the excel file to perform the hypothesis test

h0: p = 0.73

ha: p > 0.73

where p is the population proportion of all freshmen intramural participants that are retained to the next school year

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
