Answer:
Step-by-step explanation:
For this case we want to find this probability:
Because they want the area to the left of the value. We need to remember that the normal standard distribution have a mean of 0 and a deviation of 1.
We can use the following excel code: =NORM.DIST(-1.55,0,1,TRUE)
And we got:
The other possibility is use the normal standard table and we got a similar result.
well, looking at the picture of this vertically opening parabola, it has a vertex at 0,0 and it passes through 2,1 hmm ok
Answer:
The following are the answer to this question:
Step-by-step explanation:
In the question some data is missing, which is defined in the attached file please find it.
The table for point a:
plot for the Stem-and-leaf:
0 3 4 5 7 4
1 2 2 4 4 5 7 7 7
2 0 3 4 4 5 8 6
3 3 4 7 9 4
4 1
In point b:
Its distributed skewed is correct because in its points 1 is a tail on its right side.
