Answer:
There is enough evidence to support the claim
Step-by-step explanation:
We are conduction a hypothesis test for dependent samples. We want to see if there was a change in the test subjects cholesterol levels.
For our situation:
n = 64
d = 0.7
s = 1.72
µ(d) = 0
The hypothesis are:
H0: µ(d) = 0
Ha: µ(d) > 0
This is a right tailed test.
We are testing at the 1% level of significance. Our critical region is z > 2.325
If our test statistic is in this region, we will reject the null hypothesis

Hi there!
To solve this problem, we should simplify.
0.06x - 0.18 = 0.12
First, we should add 0.18 to both sides:
0.06x = 0.12 + 0.18
0.06x = 0.3
Now, we can convert 0.06 into a fraction and multiply both sides of the equation by its receprical to isolate x:
0.06 = 6/100
6/100 × 100/6 = 1
0.3 × 100/6 = 30/6
x = 30/6
x = 15/3
x = 5
So, x is 5.
Hope this helps!
