A manufacturer of automobile transmissions uses two different processes. Management ordered a study of the production costs to see if there is a difference between the two processes. A summary of the findings is shown next. What is the critical value of F at the 1% level of significance?
a. 9.46
b. 8.29
c. 8.18
d. 4.61

b. 8.29

Step-by-step explanation:

Hello!

The objective is to study both processes to see if there is any difference between the costs of manufacturing.

An ANOVA was conducted for the variable:

Y: cost of manufacturing automobile transmissions

Factor: Process

Treatments: 1 and 2

The statistic for this test is

Where

k= number of treatments

n= total number of observations

Degrees of freedom of the treatments: k-1= 2-1= 1

Degrees of freedom of errors: n-k= 20-2= 18

The critical region for this analysis is always one tailed to the right.

I hope this helps!

1696 hundred thousand

step-by-step explanation:

the degrees would remain the same ( the number to the left of the decimal point.

the multiply the decimal by 60 to get the minutes and use the numbers to the left of the decimal point.

then multiply the decimal portion of that by 60 for the seconds and round off as needed.

39 .956652

the 39 remains the degrees.

the minutes = 0.956652 x 60 = 57.39912

the minutes = 57

the seconds = 0.39912 x 60 = 23.95 = 24 ( rounded to nearest tenth)

so 39.956652 = 39 degrees, 57 minutes and 24 seconds

-75.159809

the -75 remains the degrees

the minutes = 0.159809 x 60 = 9.58854

the minutes = 9

the seconds = 0.58854 x 60 = 35.31, rounded to nearest tenth = 35.3 seconds

so -75.159809 = -75 degrees, 9 minutes and 35.3 seconds.

the first coordinate is north or south, since it it positive it is north.

the second number is east or west, because it is negative it is west.

39 degrees, 57 minutes and 24 seconds n

-75 degrees, 9 minutes and 35.3 seconds w
