Answer:
Step-by-step explanation:
Answer:
The measure of the sum of interior angles of a 11-gon is
.
Each interior angle is approximately
.
Step-by-step explanation:
A convex polygon has the measure of each interior angles to be less than
.
But,
sum of interior angles of polygon = (n - 2) x 
where n is the number of sides of the polygon.
For a convex 11-gon, we have;
sum of angles of a 11-gon = (11 - 2) x 
= 9 x 
= 
Sum of angles of a 11-gon = 
To check: convex polygons' interior angles are less than
.
so that,
each interior angle of 11-gon = 
= 
Answer:
1. b. 14.6 ± 7.38
2. b. 3.43
3. b. 0.01 < P-value < 0.05
4. b. There is sufficient evidence to reject the null hypothesis.
Step-by-step explanation:
The hypothesis test is used to test the null hypothesis against the alternative hypothesis. The p value of the test determines whether to accept or reject the null hypothesis. In the given scenario the p value is less than 0.05 so there is sufficient evidence against the null hypothesis in favor of alternative hypothesis.
