Answer:
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 108
Sample mean,
= 107
Sample size, n = 110
Alpha, α = 0.02
Population standard deviation, σ = 7
Formula:
Putting all the values, we have

The test statistic is -1.50
7.5 i think not 100% sure tho
Answer:$3334.5
Step-by-step explanation:
A=p(1+r/100)^n
A=1400(1+7.5/100)^12
A=1400(1.075)^12
A=1400×2.381
A=$3334.5
Answer:

Step-by-step explanation:
The given function is

We want to find all values of x for which:
f(x) is greater than or equal to 14.
This implies;

Subtract 13 from both sides;


By definition of the absolute value function,

Divide through the first inequality and and reverse the inequality sign:
