The appropriate statistical test for whether the mean rating of guilts are greater for unattractive defendants than for attractive is:
B. 1 tailed t-test.
<h3>What are the hypothesis test?</h3>
At the null hypothesis, it is tested if the mean rating of guilt will not be higher for unattractive defendants than for attractive defendants, that is:
At the alternative hypothesis, it is tested if the rating is greater, that is:
We are comparing the means, hence a t-test is used. We are testing if one is greater than other(not different), hence a 1-tailed test is used, and option B is correct.

- 3/8 + 4/9
= LCM = 72
= - 3 * 9/ 8 * 9 = -27/ 72
= 4 * 8 / 9 * 8 = 32 / 72
= (-27 + 32)/ 72
= 5/72

If it's relationship Akira : Business A. = 7:5
The part of Akira is 7k
and the part of the Business A. is 5k
Then
7k+5k=12k => 12k=1,800,000 => k= 1,800,00/12=150,000$
Akira part is 7k= 7 * 150,000 = 1,050,000$
Good luck!!!!
Answer:
She rode her bike 20 miles... I believe this may be a trick question.
Step-by-step explanation:
Let's break down this problem...
If she is going at a rate of 5 miles per hour while walking than the maximum she could have walked in 5 hours is 25 miles.
If Angela rode her bike for 20 miles, and the got off her bike and walked "<em>the rest of the way</em>" then she should have walked 50 miles. However as we already know her rate is 5 miles per hour while walking, and therefore could only have covered half that distance in 5 hours.
Is this a multiple choice question? Is there any misssing informaation?
