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.

(-1,-0.5)

step-by-step explanation:

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.  

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral
