Answer:
And we want this probability:
And using the normal standard distribution or excel we got:
And the best option would be:
D 0.0233
Step-by-step explanation:
For this case we have the following parameters:
And we select a sample size of n=13. And we want to find this probability:
We can assume that the distribution for this case is normal and then we can use the z score formula given by:
And if we replace the data given we got:
And we want this probability:
And using the normal standard distribution or excel we got:
And the best option would be:
D 0.0233
3/5 x 3/5
=9/25
You have to multiply the 2 numerators (top) and then the 2 denominators (bottom)
Can u be more specific on the options? Cuz there’s nothing for ABCD.
