It is to insure the experiment does not have bias.
Here is all you need for b)
Answer:
The correct answer is : C
Step-by-step explanation:
Answer:
The mean for the sample mean distribution is 297 minutes.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, a large sample size can be approximated to a normal distribution with mean
and standard deviation
.
Using the Central Limit Theorem for Means, what is the mean for the sample mean distribution?
The mean is the same as the population mean, that is, 297 minutes.
Answer:
(35,0)
Step-by-step explanation:
Consider the diagram below, the starting point is given as A and the finish point given as C.
Using similar right-angle triangle, we have that:

Therefore to find the point where Derek stops at C, we first determine the distance |AC|
|AC|=7+28=35
The Coordinates at C where Derek stops is (35,0)
