Answer:

H_0:  \bar X = 10\\H_a: \bar X >10

Step-by-step explanation:

given that Nan Compos-Mentis, a technical consultant, claims that she can increase average hourly productivity for the fabricators at Stryker Manufacturing by more than 10 units per worker.

To support her claim, Nan plans to select a sample of workers, provide the workers in the sample with special training, and then use results from the sample in a hypothesis test designed to establish whether the training has had the desired effect.

Here her matter of interest is whether training improves the mean score of hourly productivity

Hence the hypotheses should be

H_0:  \bar X = 10\\H_a: \bar X >10

A right tailed test.

PLEASE HELP ASAP!!!!!!!!!!!!!!!!!!!!!

The number in parenthesis after f is the x coordinate. Basically, it says which y coordinate is tied with an x value. In choice a, it says that when x is 0 y is 3, etc.

So, you can look at the graph to see which answer choice has a point from the graph. Choice a says (0,3), and that does not match. Choice b says (5,-1) and that does match. So the answer is B.

*(x,y)*
