Amachine that is programmed to package 1.20 pounds of cereal is being tested for its accuracy in a sample of 36 cereal boxes, the sample mean filling weight is calculated as 1.22 pounds. the population standard deviation is known to be 0.06 pound. identify the relevant parameter of interest for these quantitative data

The standard deviation

Step-by-step explanation:

Is the most relevant parameter because permit analyze the performance of the machine. Of this parameter we conclude that the machine is adding, on average, 0.06 pounds more than the mean, which is 1.22.

The machine is filling, on average, much more of cereal than the parameter programmed.

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

i got 142 as my answer
