a. A square root is the reverse of square, which means you need to find the number that when multiplied by itself equals the number you are square rooting. So, when we put sqrt(3) in to the calculator, we get 1.73205080757
We need to simplify it in the thousandths place, which is held by a two. The number in the ten thousandths place is a zero, so the 2 stays the same. Your answer for question a is 1.732
b. This question is asking for what number you think or pi is. The number pi is an indefinite number that seems to have no end. The longest amount of the number I can remember is 3.14159265
We need to round it to the thousandths place and the number held in the ten thousandths place is a 5, so we add one more to the number in the thousandths place. Our number is 3.142.
Answers:
a. 1.732
b. 3.142

Solution :
Assuming
We have to test
Against
Level of significance,
= 420.6107
Under , the t-statistics is as follows:
= 0.90
DF = (25 + 20 - 2)
= 43
P-value of the test = 0.375
Since the p value is more than 0.05, we fail to reject our null hypothesis.
