A study is conducted to investigate whether customer satisfaction is greater among computer companies that offer tech support versus those that do not offer tech support. A random sample of 50 customers are selected from among those that purchased computers that offer tech support. A separate random sample of 40 customers are selected from among those that purchased computers that do not offer tech support. The study found that the mean satisfaction rating was significantly greater among customers that purchased computers that offer tech support. Which of the following is the best description of this study?
A) An experiment using a completely randomized design.
B) An experiment using a randomized block design.
C) An experiment using a matched pairs design.
D) An observational study using a simple random sample.
E) An observational study using a stratified sample.
Answer:
E) An observational study using a stratified sample.
Step-by-step explanation:
This study is not an experiment because the customers were not subjected to any treatment but just observation from those selected. Also, the sampling method used was stratified sampling because we see that random samples were selected independently from two unique populations which are population of those that purchased computers and those that offer tech support.
Therefore the correct option is E.

7003 divided by 5 show work :)
Answer:
1400.6
Step-by-step explanation:
7003 divided into 5 groups puts 1400.6 in each group
Answer:
1400.8
Step-by-step explanation:
5/7003
1. 7-5 (5 goes in once)
2. you can't do 2-5 so drop down the 0. (20)
3. 5 goes into 20 4 times. add the 4 to the top
4. put the zero in since it doesn't go with anything (it should look like 1400)
5. drop the 3 down but since 5 can't go in add a zero (and a decimal to your answer on top) - 1400.
6. 5 goes into 30, 8 times.
7. final answer: 1400.8

A scale model of an object of 1 cm : 2 ft. The actual object is 11 feet tall. How tall is the model
Answer:
5.5 cm
Step-by-step explanation:
Use compound interest to find the total amount for $845 at 1.25% for 6.5 years
Answer:
$911.02
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 1.25%/100 = 0.0125 per year,
then, solving our equation
I = 845 × 0.0125 × 6.25 = 66.015625
I = $ 66.02
The simple interest accumulated
on a principal of $ 845.00
at a rate of 1.25% per year
for 6.25 years is $ 66.02.

Here are some fractions.
10/15
4/6
12/18
10/16
16/24
One of these fractions is NOT equivalent to
2/3
a) Which fraction?
b) Work out 1/8 + 3/4
Give your answer in its simplest form.
Answer:
10/16 is not equivalent to ⅔.
⅛+¾=⅞
Step-by-step explanation:
To simplify to simplest form find the GCF for both and divide on each side.
[tex] \frac{10}{15} = \frac{2}{3} [/tex]
the GCF is 5, so you divide the numerator and denominator by 5 to get 2/3.
[tex] \frac{4}{6} = \frac{2}{3} [/tex]
When you divide the numerator and denominator by 2 (GCF) it would be ⅔.
[tex] \frac{12}{18} = \frac{2}{3} [/tex]
when you divide both the numerator and denominator by 6 (GCF) you get ⅔.
[tex] \frac{10}{16} = \frac{5}{8} [/tex]
when you divide the numerator and denominator by 2 (gcf) you get ⅝.
therefore, 10/16 is not equivalent.
[tex] \frac{1}{8} + \frac{3}{4} = [/tex]
Find the LCM
Least Common Multiple is 16.
8: 8, 16
4: 4, 8, 12, 16
[tex] \frac{2}{16} + \frac{12}{16} [/tex]
for ⅛ you multiply the numerator and denominator by 2 to get 2/16. do the same with 3/4 but with 4 to get 12/16
[tex] \frac{2}{16} + \frac{12}{16} = \frac{14}{16} [/tex]
you can simplify by dividinv both sides by 2 to get 7/8.
