Answer:
The answer to your question is x = 40°
Step-by-step explanation:
According to the picture we determine that the triangle to the right is isosceles so two of its angles are equal.
Remember that the sum of the internal angles in a triangle equals 180°
2x° + 100° = 180
- Subtract 100 in both sides
2x + 100 - 100 = 180 - 100
- Simplify
2x = 80
-Divide both sides by 2
2/2 x = 80/2
Simplify and result
x = 40°
Answer:
C) Fail to reject the claim that the mean temperature is equal to 43°F when it is actually different from 43°F.
Options:
A) Fail to reject the claim that the mean temperature is equal to 43°F when it is actually 43°F.
B) Reject the claim that the mean temperature is equal to 43°F when it is actually 43°F.
C) Fail to reject the claim that the mean temperature is equal to 43°F when it is actually different from 43°F.
D) Reject the claim that the mean temperature is equal to 43°F when it is actually different from 43°F.
Explanation:
The null hypothesis H0: µ=43°F (a true mean temperature maintained by refrigerator is equal to 43°)
The alternative hypothesis Ha: µ<>43 (a true mean temperature maintained by refrigerator is not equal to 43).
A type II error does not reject null hypothesis H0 when it is false. Therefore, the type II error for the test fails to reject the claim that the mean temperature is equal to 43°F when it is actually different from 43°F.
