Answer:- AAS postulate
Explanation:-
- AAS postulate tells that if two angles and a non-included side of a triangle to equal to the two angles and a non-included side of another triangle then the two triangles are said to be congruent.
Given:- One angle and one side of a triangle is equal to the one angle and one side of the other triangle.
We see there is one more pair of equal angles as they are vertically opposite angles . [See the attachment]
⇒ there is a triangle where two angles and a non-included side of a triangle to equal to the two angles and a non-included side of another triangle then the two triangles are said to be congruent.
⇒ The triangles are congruent [ by ASA postulate]
Using confidence interval concepts, it is found that:
a) The point estimate is the sample mean.
b) The confidence interval is:
c) If $1411 is between the bounds of the interval yes, otherwise no.
--------------
- At item a, it asks to provide a point estimate for the population mean, which is the sample mean
--------------
Item b:
- In the spreadsheet, it is possible to find the <em>standard deviation for the sample</em>, thus, the t-distribution is used.
- The confidence interval will be given by:
In which:
is the sample mean.
- T is the critical value, from the t-distribution, with a two-tailed area of
and n-1 degrees of freedom.
- s is the standard deviation for the sample.
- n is the sample size.
--------------
Item c:
We have to check if 1411 is between and
.
- If it is, the interval includes the National Average, otherwise, it does not.
