Amachine that grinds valves is set to produce valves whose lengths have mean 100 mm and standard deviation 0.1 mm. the machine is moved to a new location. it is thought that the move may have upset the calibration for the mean length, but that it is unlikely to have changed the standard deviation. let µ represent the mean length of valves produced after the move. to test the calibration, a sample of 100 valves will be ground, their lengths will be measured, and a test will be made of the hypotheses h0: µ=100 versus h1: µ≠100. find the rejection region if the test is made at the 5% level? if the sample mean length is 99.97 mm, will h0 be rejected at the 5% level?

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

the option best identifies the textual evidence that supports this conclusion is c.) when an argument is over, how many weighty reasons does a man recollect which his heat and violence made him utterly forget? in order to recognize textual evidence is to identify the topic sentence where the author states the main idea. textual evidence is what supports the topic sentence or main idea of a passage.
