Answer:
Correct option: B
Step-by-step explanation:
The professor can perform a One-mean <em>t</em>-test to determine whether the average score of the students in his class is more than the average score of all the students attending university.
A <em>t</em>-test will be used instead of the <em>z</em>-test because the population standard deviation is not provided instead it is estimated by the sample standard deviation.
The hypothesis for this test can be defined as follows:
<em>H₀</em>: The average score of the students in his class is not more then the entire university, i.e. <em>μ ≤ 35</em>.
<em>Hₐ</em>: The average score of the students in his class is more then the entire university, i.e. <em>μ > 35</em>.
Given:

The test statistic is:

Thus, the correct option is (B).

Answer:
45%
Step-by-step explanation:
Given data
Last year, the company sold a total of 5,340 ovens
This year, they sold 7,743 ovens
Percent increase= final-initial/initial*100
substitute
Percent increase= 7,743-5,340/5,340*100
Percent increase= 2403/5,340*100
Percent increase=0.45*100
Percent increase=45%
Hence the increase is 45%
I think maybe 0.3 then 2 1/2 and then 15
