Express the alternative hypothesis in symbolic form. an automobile technician claims that the mean amount of time (in hours) per domestic car repair is more than that of foreign cars. assume that two samples are independent. let the domestic car repair times be the first population and the foreign car repair times be the second population.

: mu1-mu2=0

: mu1-mu2>0

Step-by-step explanation:

Let mu1 be the mean amount of time (in hours) per domestic car repair

and mu2 be the mean amount of time (in hours) per foreign car repair

According to the claim of the automobile technician, the mean amount of time (in hours) per domestic car repair is more than that of foreign cars.

Then null and alternative hypotheses can be stated in symbolic form as

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.

step-by-step explanation:
