The answer x = 11 is correct for problem 4. Nice work.
Use this x value to find the answer in problem 5. From problem 4, we're told that Romeo runs at a speed of 5 m/s. If he runs for x = 11 seconds,then he runs a total distance of:
5*x =(5 m/s)*(x meters) = (5 m/s)*(11 seconds) = 5*11 = 55 meters
The answer to problem five is 55 meters

Answer: Two-tailed test.
Population mean is the parameter which is tested.
Step-by-step explanation:
Given : 

We know that , the alternative hypothesis (
) indicates kind of the hypothesis test we need to perform whether left-tailed, right-tailed, or two-tailed.
Here, the alternative hypothesis (
) is two-tailed, so the hypothesis test is a two-tailed test.
Also, the parameter present in the hypothesis is
which is a symbol to represent the population mean.
Thus , Population mean is the parameter which is tested.
