Answer:
Choice A: there is insufficient evidence to conclude that the mean for the fiber content is less than 2.5 gms.
Step-by-step explanation:
From the graphs given the more appropriate is one sample t- test
One sample t- test is used and the results are
Hypothesis Test Fiber
Sample Mean 2.62
Sample St. Dev 3.492
Degrees of Freedom 24
t- test statistic 0.1718
p- value 0.5675
the critical region for this test at ∝= 0.05 is t < -1.711
There is not enough evidence to reject the null hypothesis.
Since the calculated t= 0.1718 does not fall in the critical region the null hypothesis is accepted that the mean fiber content is not less than 2.5 grams.T
First, we need to use the distributive property to simplify the expression. So, that means we have to multiply the 4 by all of the integers and variables inside the parentheses.
If done correctly, your expression should be 6+12x-8+5
Next, we should combine all of the constant terms (just numbers without variables), also known as combining like terms.
If done correctly, your expression should be 12x+3.
This matches answer B. 12x+3
