A student at a Midwest college is interested in whether Psychology majors spend more or less time studying than English majors. She randomly selects 8 Psychology majors and 8 English majors and determines their weekly studying time. The following are the scores. Note one person dropped out of the study.
Psychology Majors 16 12 13 10 9 10 8
English Majors 10 25 15 17 23 14 19 18
An analysis is being conducted using the Mann-Whitney U test. If a = 0.052 tail, Ucrit =
A) 07
B) 49
C) 10
D) 46

C.10

Explanation

From table critical value of U when n1 is 7 and n2 is 8 and symbol alpha is 0.05 then Ucrit=10

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .

5050 i think
