Answer:
(15.23,41.016)
Step-by-step explanation:
WE must determine the mean of the data set: Which is the sum of the set divided by the number in the set.
We must also determine the standard deviation: Which is the square root of the variance and the variance is the sum of squares of the sample number minus the mean divided by the number if the set data:
The 95% confidence interval is defined as: The mean ± 1.96*standard deviation divided by the sqaure root of the number of data in the set:
The confidence interval for this data set is (15.23,41.016)
Answer:
Step-by-step explanation:
Because 12 is 3 times as large as 4, that means that the distance traveled in this time will be 3 times as large as the distance traveled in 4 minutes. This is 3/4 * 3 = 2.25 miles. The same goes for 20 minutes, only it is 5 times bigger, and therefore the distance traveled is 3/4 * 5 = 3.75 miles. Hope this helps!
