Step-by-step explanation:
Answer: False
Step-by-step explanation:
We know that , If p-value < 
, we reject the null hypothesis .
If p-value ≥ , we are fail to reject the null hypothesis .
As per given , we have
The p value for an independent samples t-test is 0.043.
The level of significance is 
Since , 0.043 < 0.05.
i.e. p-value <
It means we reject the null hypothesis .
It means the null hypothesis is false.
Hence , the correct decision in this scenario is to favor the null hypothesis : False

Problem 12
Comment
A cyclic quadrilateral (a 4 angled quadrilateral where all 4 corners touch the circumference of a circle), has the property that opposite angles add up to 180 degrees.
Formula
4x + 9 + 3x + 3 = 180 Collect like terms
Solution
4x + 3x + 9 + 3 = 180 Combine
7x + 12 = 180 Subtract 12 from both sides
7x + 12 -12 = 180 - 12 Combine
7x = 168 Divide by 7
7x/7 = 168/7
x = 24
Answer
x = 24
Problem 13
Comment
Same comment as was given for problem 12
Formula
3x + 2 + 3x - 32 = 180 Collect like terms
Solution
3x + 3x +2 - 32 = 180 Combine
6x - 30 = 180 Add 30 to both sides
6x -30+30 = 180 + 30
6x = 210 Divide by 6
6x/6 = 210/6
x = 35
Answer
x = 35
