The values in the following matrix are treatment means from a two-factor study. One of the means is missing. What value for the missing mean would result in no main effect for Factor A? B1 B2
A1 6 8
A2 12 ?
a. 14
b. 10
c. 12
d. 2

(Please explain)

D) 2

the value for the missing mean would result in no main effect for Factor A is 2

Step-by-step explanation:

Given that;

              B1             B2

A1            6               8          

B1            12               ?

To find the missing mean;

lets missing mean be x

Here mean of A1

( 6 + 8 ) / 2 = 14 / 2 = 7  

Now mean of A2

(12 + x ) / 2 = 7

x + 12 = 14\x = 14 -12 = 2

Therefore the value for the missing mean would result in no main effect for Factor A is 2

so option d) is the correct answer

step-by-step explanation:

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
