Answer:

8 miles.

Step-by-step explanation:

Biking at 8 miles per hour for 1/4 an hour is equal to biking 2 miles.

Riding the train at 24 miles per hour for 1/4 an hour is equal to riding 6 miles.

2 miles + 6 miles = 8 miles.

Answer:

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

F= \frac{MS_{Treatment}}{MS_{Error}} ~~F_{k-1; n-k}

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 <u>always</u> one tailed to the right.

F_{k-1;n-k;1-\alpha }= F_{1;18;0.90}= 8.28

I hope this helps!
