Step-by-step explanation:
the figure I've circled is similar to yhe figure shown because when we compare the measurements of the length and breadth of both rectangles, we can see that both the rectangles have the see me measurements, 3ft and 7ft. The only difference however, is that the figures have been rotated differently, the figure shown is kept vertically, on the other hand, the figure I've circled is rotated horizontally.
hope that helps...
Answer:
The confidence level of the study is 99.9%
The confidence level is 99.9% of the margin error is 8%
Step-by-step explanation:
<u>Explanation</u>:-
Candy has observed 250 sports cars
The sample size 'n' = 250
Sample proportion 'p' = 15% = 0.15
The margin of error = 8% = 0.08
<em>The margin of error is determined by </em><em> = </em><em />
<em> </em><em />
<u>Conclusion</u>:-
The z- score of 99.9% level of significance = 3.54 for two tailed test
<em>Hence the confidence level is 99.9% of the margin error is 8%.</em>
