Answer:
Step-by-step explanation:
Given that:
Population Mean = 7.1
sample size = 24
Sample mean = 7.3
Standard deviation = 1.0
Level of significance = 0.025
The null hypothesis:
The alternative hypothesis:
This test is right-tailed.
Rejection region: at ∝ = 0.025 and df of 23, the critical value of the right-tailed test 
The test statistics can be computed as:
t = 0.980
Decision rule:
Since the calculated value of t is lesser than, i.e t = 0.980 < , then we do not reject the null hypothesis.
Conclusion:
We conclude that there is insufficient evidence to claim that the population mean is greater than 7.1 at 0.025 level of significance.
Answer:
y = 13x
Step-by-step explanation:
If "y" represents how much he earns total
and "x" represents the number of games sold
then the equation is 
which can be simplified to 
Angle a is 35 degrees angle b is 55 degrees angle c is 110 degrees

Step-by-step explanation:
<u>Step 1: Define</u>
Point P(1, 3)
Point Q(7, 7)
<u>Step 2: Identify</u>
P(1, 3) → x₁ = 1, y₁ = 3
Q(7, 7) → x₂ = 7, y₂ = 7

<u>Step 3: Find Midpoint</u>
Simply plug in your coordinates into the midpoint formula to find midpoint
- Substitute in points [Midpoint Formula]:
- [Midpoint] Add:
- [Midpoint] Divide:
Answer:
The answer is (4,14) because both lines pass through this point.
