1. A researcher uses an ANOVA to evaluate the mean difference between two treatment conditions and obtains F = 4.00 with df = 1, 16. If an independent-measures t statistic had been used instead of the
ANOVA, then whatt value would be obtained and what is the df value for t?
A. t = 16 with df = 17
B. t = 2.00 with df = 17
C. t = 16 with df = 16
D. t = 2.00 with df = 16
E. None of the above

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58

the answer is z7+8/5
