Which graph represents y=square root of x-4
2 answers:
For this case we have the following function:
y = root (x-4)
It is a function in the form of a parabola.
The domain of the function is:
[4, inf)
To make the graph we can make use of a computational tool and verify that the graph corresponds with the mentioned characteristics.

Answer:
Step-by-step explanation:
The confidence interval to estimate the population mean is given by :_
Given : Sample size : n= 60 , the sample is a large sample (n>30), so we can apply z-test.
Sample mean =
Standard deviation :
Level of confidence:
Then, critical z-value =
Then, a 95% confidence interval estimate of the population mean will be
Hence, the 95% confidence interval to estimate the population mean = .
