A machine manufactures bolts that are supposed to be 3 inches in length. Each day a quality engineer selects a random sample of 50 bolts from the day's production measures their lengths, and performs a hypothesis test of H : μ=3 versus H1: μ#3 , where μ is the mean length of all the bolts manufactured that day. If He is rejected at the 5% level (or, =0.05), the machine is shut down and recalibrated. a. [35 points] If the sample mean is x = 3.011 inches and the sample standard deviation 0.0 inches, show and NUMBER all 5 steps of the hypothesis- testing procedure (in the handout) to decide whether or not the machine needs to be recalibrated. Include the case (l, ll, lll or IV) that appropriately categorizes the situation described in step 3. Also, state whether or not you are using the central limit theorem in step 3.

554.4

step-by-step explanation:

44*12.6=544.4

what's that

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

ok so the answer to your question is simple as long as you look at the different dimensions that contain the exemplary letters that combined in the right order give you words that eventually within the 5th dimension will conform and give you the correct answer to your question. hope i , stop looking at this easily, look at it with a spectral view.
