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

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.

I hope this helps!
Question??
Dr. Sox drives through two stoplights on her way to work. The first light is green for 20 seconds out of each minute. The second light is green for 35 seconds out of each minute. What is the probability that Dr. Sox will hit two green lights?
Explanation;
Since this is an AND situation, we MULTIPLY the probabilities.
Answer/Explanation:
First light green:
P
1
=
20
60
=
1
3
Second light green:
P
2
=
35
60
=
7
12
Both lights green:
P
=
P
1
×
P
2
=
1
3
×
7
12
=
7
36
Of course, this is assuming that there is no "green wave" policy, or the two probabilities would not be independent
64 and 28 have a GCF of 4, since 64 = 4 x 16, 28 = 4 x 7, and 7 and 16 have no factors other than 1 in common. Knowing that, we can rewrite 64 + 28 as
4 x 16 + 4 x 7
and then use the distributive property to rewrite it again as
4 x (16 + 7)
Answer:
Irrational because it is a decimal that doesn´t repeat or terminate
