A national manufacturer of ball bearings is experimenting with two different processes for producing precision ball bearings. It is important that the diameters be as close as possible to an industry standard. The output from each process is sampled and the average error from the industry standard is measured in millimeters. The results are presented next.
Process A Process B
Sample mean 2.0 3.0
Standard deviation 1.0 0.5
Sample size 12 14
The researcher is interested in determining whether there is evidence that the two processes yield different average errors. The population standard deviations are unknown but are assumed equal. If What is the decision if we use 1% level of significance?
a. Fail to reject the null hypothesis and conclude the means are different.
b. Reject the null hypothesis and conclude the means are different.
c. Fail to reject the null hypothesis and conclude the means are the same.
d. Reject the null hypothesis and conclude the means are the same.
Answers
Answer:
b). Reject the null hypothesis and conclude the means are different.
Step-by-step explanation:
A hypothesis is characterized as null when the data/statistics display that there is no distinction between the particular features of the groups. As per the details provided, the decision would be to 'reject/deny the null hypothesis and deduce that the means of the processes are different.' This shows that there is no association among the variables due to the distinction in the means of the two processes and other data provided. Thus, option b is the correct answer.

Jason drove 8 4/5 miles to a subway station. He then 15 /6 miles by taxi to attend a meeting. How many total miles did he travel?
Answers
Answer:
Option A: (23 + 29/30) miles
Step-by-step explanation:
Here we just need to add two mixed numbers.
(8 + 4/5) miles and (15 + 1/6) miles.
To add these, we just separate between the whole part and the fraction part:
(8 + 4/5) miles + (15 + 1/6) miles
= (8 + 4/5 + 15 + 1/6) miles
= (8 + 15 + 4/5 + 1/6) miles
= (23 + 4/5 + 1/6) miles
Now we need to find a common multiple between 6 and 5.
So, only analyzing the fraction part of the sum, we can rewrite:
4/5 + 1/6
= 4/5*(6/6) + 1/6*(5/5)
(notice that we are multiplying both numbers by one, so we do not change the expression's value)
= (4*6)/(5*6) + (1*5)/(6*5)
= 24/30 + 5/30
So now both fractions have the same denominator.
Then, replacing that in the sum equation we get:
(23 + 4/5 + 1/6) miles = (23 + 24/30 + 5/30) miles
= (23 + 29/30) miles
Then the correct option is option A.

Answer:
d. m∠Q = 75 degrees
Step-by-step explanation:
The sum of the angles in a triangle is 180°. This triangle is marked to show it is an isosceles triangle, so the two base angles have the same measure.
∠P +∠Q +∠R = 180°
x° +(2x +15)° +(2x +15)° = 180°
5x = 150 . . . . . . . . . . . . . . . . . . . divide by °, subtract 30
x = 30 . . . . . . . . . . . . . . . . divide by 5
m∠Q = (2x +15)° = (2(30) +15)°
m∠Q = 75°

We will use the formula P = 2L+2W:

P = 2(5x-y)+2(2x+3y)
P = (10x-2y)+(4x+6y)

Answer:
8. C) 24.2
9. A) 8.1
Step-by-step explanation:
8. The radius is shown as being 7.8 +4.3 = 12.1, so the diameter x is ...
d = 2r
x = 2(12.1) = 24.2
__
9. The unknown leg (y) of the right triangle can be found from the Pythagorean theorem.
y² +11.7² = 12.5² . . . . . the radius is half the diameter
y = √(156.25 -136.89) = √19.36 = 4.4
Then the segment of interest is ...
x + y = 12.5
x = 12.5 -4.4 = 8.1
Answer:
the length of a segment indicated.

Proportional is where everything will match
so we have 2x3=6 5x3=15 8x3=24 11x3=33
This works because it continues the same line of multiplication (x3).
But like B, you start with 4,4=16 which works, but now you have 5x4=21, which will not work because 5x4 will never equal 21
