Then we can find the mean and the standard deviation with the following formulas:
> mean(a)
[1] 50.72451
> sqrt(var(a))
[1] 7.470221
Step-by-step explanation:
For this case first we need to create the sample of size 20 for the following distribution:
And we can use the following code: rnorm(20,50,6) and we got this output:
> a<-rnorm(20,50,6)
> a

<em>5 to the 2nd power times 5 to the 2nd power is equivalent to 625</em>
<h2>Explanation:</h2>In this case, we have the following statement:
<em>5 to the 2nd power times 5 to the 2nd power. </em>In a mathematical language:
From product rules, we know that:
Applying this rule to our problem:
<em>5 to the 2nd power times 5 to the 2nd power is equivalent to 625</em>
