Answer:
C. Graph C
Step-by-step explanation:
To easily find out which graph correctly displays the data from the list and table, note, the frequency of each color that in ascending order.
The color with the highest frequency would have the longest bar, followed by the 2nd highest, then the third, and so on. Thus, frequency should tally with the length of the bar.
From the table given, the top 3 are:
Pink polka dots => 12
Purple => 8
Ted and orange stripes => 7
Green => 6
Blue and gray => 4
Yellow => 3
The graph that has length of bars that corresponds to the frequency of the colors is graph C
Answer: There is a 90% chance that the true proportion of teenagers who drive their own car to school will lie in (0.5907, 0.9093).
Step-by-step explanation:
Interpretation of a% confidence interval : A person can be a% confident that the true population parameter lies in it.
Here, A 90% confidence interval to estimate the true proportion of teenagers who drive their own car to school is found to be (0.5907, 0.9093).
i.e. A person can be 90% confident that the true proportion of teenagers who drive their own car to school lies in (0.5907, 0.9093).
Hence, correct interpretation is : There is a 90% chance that the true proportion of teenagers who drive their own car to school will lie in (0.5907, 0.9093).
