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.
Rule: Any positive number is always larger than any negative number.
For example, 10 is larger than -2. So we write 10 > -2.
The same goes for 8 & 1/4 vs -8 & 1/4. It doesn't matter if we involve fractions or decimals.
Visually, positive numbers are to the right of 0 on the number line. Negative numbers are to the left of 0.
Stuff on the right is larger than stuff on the left.
Answer:
x = -48.
Step-by-step explanation:
40 + 4x = 3x - 8
4x - 3x = - 8 - 40
x = -48.
I believe it is A because line segment AC is equal to line segment BD, and AE and BF are also the same
