Answer:
a) how much difference in number of mean is 2.2
b) standard error of sample mean = 0.8
c) the test statstistical value is greater than the critical value ,hence we reject the null hypothesis. we can conclude that the treatment thus have a significant effect
Step-by-step explanation:
There should be 6 per number
ex.
1234
1243
1342
1324
1432
1423
What numbers are inside both circles?
The answer is A.
The new slope is 3, but the y-intercept doesn't change.
AB = CB
Because they are congruent
Therefore CB = 5.9
Given perimeter = 17
CB+BE+ED+DC = 17
5.9 + BE + 2.8 + 5.6 = 17
BE + 14.3 = 17
BE = 17 - 14.3
= 2.7
Hope I helped
If I did please give brainlest answer
Thanks
