You wonder whether the ratings of movies that are dramas differ, on average, from the ratings of movies that are comedies. you retrieve the ratings of five comedies and five dramas from the internet movie database (imdb). the ∑r for dramas is 25 and for comedies it is 31. using a p level of 0.05, what conclusion should you draw on the basis of these results? a. given that the smallest of the σr (25) is not equal to or less than the critical value of 2, you fail to reject the null hypothesis. you do not have evidence that the ratings of dramas and comedies differ.
b. given that the smallest u (u = 9) is not equal to or less than the critical value of 2, you fail to reject the null hypothesis. you do not have evidence that the ratings of dramas and comedies differ. c. given that the largest of the σr (31) is greater than the critical value of 2, you reject the null hypothesis. the ratings of dramas and comedies differ.
d. given that the smallest of the σr (25) is greater than the critical value of 2, you reject the null hypothesis. the ratings of dramas and comedies differ.

step-by-step explanation:

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
