Answer: A. We are 99% confident that the interval from 4.1 to 5.6 actually does contain the true value of mu.
Step-by-step explanation:
The correct interpretation of a 99% confidence interval is that we are 99% confident that the true population mean falls in it.
Given 99% confidence interval :
Then, the correct interpretation : We are 99% confident that the interval from 4.1 to 5.6 actually does contain the true value of mu.

Answer:
The conversion of 2000 ft per min into miles per hour is 2.268 miles per hour .
Step-by-step explanation:
Given as :
The speed = s = 2000 ft per min
Now, ∵ 5280 feet = 1 miles
so, 1 feet = miles
∴ 2000 feet = × 2000 miles
i.e 2000 feet = 0.378 miles
<u>Again</u>
∵ 1 minute = hour
So, The speed in miles per hour
s =
∴ s =
i.e s = 2.268 miles per hour
Hence, The conversion of 2000 ft per min into miles per hour is 2.268 miles per hour . answer
