Answer:
Step-by-step explanation:
Since n < 30, we will find the t-score and compare that to the t-score of a significance level of 1%.
Since they are asking if the difference is significant, we will have a two tailed test, with degree of freedom being 22, so our critical values are
t < -2.704 and t > 2.704
Our t-value for this situation is
t = ([µ + 5.8] - µ)/(1.4/√23)
It's µ + 5.8 because the problem told us that their levels are 5.8 mm higher than the average, so it's the average, plus 5.8
Simplify the equation...
t = 5.8/(1.4/√23)
t = 19.868
19.868 > 2.704, the evidence supports that there is significant difference between the sample and the population
Answer:

Answer:
f(x) = 3x + 26; 26 ≤ y ≤ 35
Step-by-step explanation:
This makes a linear equation.
y=mx+b
where m is the amount they want to increase each week
and b is the initial value i.e 26 clients.
Now substitute the values in the equation.
Let x=0
y=3(0)+26
y = 26
Now let x= 3
y=mx+b
y=3(3)+26
y=9+26
y=35
Thus the correct option is B.
f(x) = 3x + 26; 26 ≤ y ≤ 35 .....
Given:
The table of values.
Hours (h) Dollars (d)
1 42
2 84
3 126
4 168
5 ?
To find:
The correct statements about the table.
Solution:
From the given table it is clear that,
This pattern can be defined as
Multiply h by 42 to get d. So, option A is correct.
Using this pattern, we get
The missing value in the last row is 210. So, option D is correct.
From the given table it is clear that the rate of change is $42 per hour because dollar is increasing by 42 in every hour.
A real-world situation that is represented in the table is “Richard is a video game designer and earns $42 per hour.”
Therefore, the option E is correct.
