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:
see attachments
Step-by-step explanation:
a) A table lists the ordered pairs either by row or by column. In the attached, we have listed the x-values down a column, and the y-values the same way. (This way, we can use the same list for the map.) The table is the first attachment.
__
b) A graph is simply a plot of the given points. The graph is the second attachment.
__
c) A map is similar to a table, but with arrows pointing to the output value for a given input. The map is the third attachment.
