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.
First, change the mixed fractions to improper fractions
9x3=27+2=29/9
5x6=30+5=35/6
Now we have 35/6 + 29/9, but we need to make the denominators equal in order to add.
35/6 x 3/3= 105/18
29/9 x 2/2= 58/18
Now we just need to add
58/18 + 105/18 = 163/18
163/18 would be your answer.
