Answer:
Step-by-step explanation:
The geometric distribution represents "the number of failures before you get a success in a series of Bernoulli trials. This discrete probability distribution is represented by the probability density function:"
Let X the random variable that measures the number os trials until the first success, we know that X follows this distribution:
In order to find the expected value E(1/X) we need to find this sum:

Lets consider the following series:
And let's assume that this series is a power series with b a number between (0,1). If we apply integration of this series we have this:
(a)
On the last step we assume that
and
, then the integral on the left part of equation (a) would be 1. And we have:

And for the next step we have:

And with this we have the requiered proof.
And since
we have that:
Answer:
-40
Step-by-step explanation:
- Negative × positive = negative
- -5 × 8 = -40
I hope this helps!
The probability of correctly rejecting the null hypothesis when the null hypothesis is false is the power
<h3>How to complete statement?</h3>
From the question, we have the following highlights
- Null hypothesis is false
- Null hypothesis is correctly rejected
The statement that represents the probability of the above highlights is power
Hence, the statement that completes the blank is power
