The critical value can be founded in the normal standard distribution table using the value of
and we got
. Replacing the info given we got:

Step-by-step explanation:
For this case we have the following info given:
represent the population deviation
represent the sample mean
represent the sample size
And we want to find the margin of error for a confidence level of 95%. So then the significance level would be
and
. The margin of error is given by:

The critical value can be founded in the normal standard distribution table using the value of
and we got
. Replacing the info given we got:

Answer:
B
Step-by-step explanation:
Sin(A) = O/H
Sin(A) = 27/45
Sin(A) = 0.6
Answer:
a = 
Step-by-step explanation:
ab + c = d
- c - c
ab = d - c
divide both sides by b
a =
