Answer:
We need to conduct a hypothesis in order to determine if the mean is greater than specified value, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
For this case the significance is 1%. So we need to find a critical value in the normal standard distribution who accumulates 0.99 of the area in the left and 0.01 in the right and for this case this critical value is:
Step-by-step explanation:
Notation
represent the sample mean
represent the standard deviation for the population
sample size
represent the value that we want to test
represent the significance level for the hypothesis test.
z would represent the statistic (variable of interest)
State the null and alternative hypotheses.

Given:
The sum of the angles in a hexagon is 720°.
To find:
(a) Equation to solve the value of x.
(b) The value of x.
(c) The measure of angle C.
Solution:
(a)
We have,
The sum of the angles in a hexagon is 720°.
Therefore, the required equation is .
(b)
On solving the above equation, we get
Divide both sides by 3.
Therefore, the value of x is 42.29.
(c)
We need to find the measure of angle C.
Therefore, the measure of angle C is 126.87 degrees.
