5y=4x+10 /:5
y=4/5 x+2
y=mx+k
m₁*m₂=-1
4/5 *m=-1
m=-5/4
y=-5/4 x+k
-5/4*(-15)+k=8
75/4 + k=8
k=32/4 - 75/4
k=-53/4=-13.25
y=-5/4 x - 53/4
61/75=0.81. 1/15=0.06. So 61/75 is greater.
Your answer is -2,146 because you have to try to get x by itself. So to do that you must subtract 2,318 and 18 from 190 to get your answer.
You divide the top by the bottom. 8/18=.44
Answer:
The conclusion, since the null hypothesis was not rejected, is that the proportion of readers of the newsletter who own a Rolls Royce is significantly close to 0.6.
Step-by-step explanation:
A newsletter publisher believes that 60`% of their readers own a Rolls Royce.
This means that the null hypothesis is:
That is, that the proportion of their readers who own a Rolls Royce is of 0.6.
A testing firm believes this is inaccurate and performs a test to dispute the publisher's claim.
The alternate hypothesis is:
After performing a test at the 0.020.02 level of significance, the testing firm fails to reject the null hypothesis. What is the conclusion regarding the publisher's claim?
The conclusion, since the null hypothesis was not rejected, is that the proportion of readers of the newsletter who own a Rolls Royce is significantly close to 0.6.
