Aplant in the manufacturing sector is concerned about its sulfur dioxide emissions. the weekly sulfur dioxide emissions follow a normal distribution with a mean of 1000 ppm (parts per million) and a standard deviation of 25. recently, a “cleaner” technology has been adopted. in such a scenario, the ceo would like to investigate whether there has been a significant change in the emissions and has hired you for advice. in other words, the ceo wants to know if the mean level of emissions is different from 1000 at the 1% level of significance. what are the critical values of the test statistic? in other words, what are the values of zlow and zhigh?

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

11

step-by-step explanation:

32.50-7.50=25

225/25=11

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
