When you take the square root of a plus number, you get 2. It is often written as +/- something.
For example sqrt 64 = +8 and - 8
(8)*(8) = 64
(-8)(-8) = 64 Remember when 2 minus' are multiplied together, you get a plus.
Oddly, when you take the cube root of something, you get only 1 answer. When you take an advanced math course, you will find out that it is three. But until you know what a complex number is, the answer is 1.

Answer:
\mu = 41.1091, 43.6109
Step-by-step explanation:
given data sets
40.2,43.1,45.5,44.5,39.5,40.2,41.0,41.6,43.1,44.9
sample mean = (sum of all value / number of value)
sample mean = 423.6/10 = 42.36
standard deviation = 2.158 given
t =1.833 for 90% confidence interval at df = n-1 = 9
90% confidence interval is given as
\mu = 41.1091, 43.6109
