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 answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )

the speed is   miles per hour > is false

step-by-step explanation:

we know that  

a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

in a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the graph shown in the figure represent a direct variation

the slope of the line represent the speed

for the point

substitute the values of x and y

the linear equation is equal to

statements

case a) it takes hours to go miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

case b) the speed is   miles per hour

the statement is false

because the speed is

case c) the unit rate for the trip is

the statement is true

because the speed is equal to the slope of the linear equation

case d) it took minutes to go the first miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct
