Answer:
H0: μ = 8.3 hours
Ha: μ > 8.3 hours
We need to remember that a type of error II if the error associated when we NO reject the null hypothesis when actually the alternative hypothesis is true. And is also known as false negative. The best answer for this case would be:
D. The manufacturer will decide the mean battery life is 8.3 hours when in fact it is greater than 8.3 hours.
Since we are FAILING to reject the null hypothesis when the true mean is actually higher than the value specified
Step-by-step explanation:
For this case we want to determine if mean running time has increased as a result of the new change so then the system of hypothesis are given by:
Note: we assume that the value to check in order to be consistent with the options is 8.3
H0: μ = 8.3 hours
Ha: μ > 8.3 hours

Answer:
B option is right
Step-by-step explanation:
These 3 will form a 3d system.
Hey there! I'm happy to help!
Let's call our number n. Here is the information we have.
n+5=5n
We subtract 5n from both sides.
n+5-5n=0
Combine like terms.
-4n+5=0
Subtract 5 from both sides.
-4n=-5
Divide both sides by -4.
n=5/4
Our number is 5/4 or 1 1/4. If you add 5 to 5/4, you get 6 1/4. If you multiply 5/4 by 5, you get 25/4 which is also 6 1/4.
Have a wonderful day! :D
