Given:
The lengths of the sides of a triangle are 6, 11, 16.
To find:
Whether the given triangles is a right angle triangle or not.
Solution:
Pythagoras theorem:
A triangle is a right angle triangle if the sum of squares of two smaller sides is equal to the square of the largest sides.
In the given triangle the length of the largest side is 16.
Square of the largest sides is:
Sum of the squares of the two smaller sides is:
Since , therefore the given triangle is not a right angle triangle.
Answer: t= 0.866
Step-by-step explanation:
Formula to find t-test statistic :
where, n= sample size
= sample mean
= Population mean
=sample standard deviation
Given : Null hypothesis : H0:μ=8.000 cm
Alternative hypothesis : H1:μ<8.000 cm , since alternative hypothesis is one-tailed , so the test is one-tailed test.
Then , the t‑statistic for this test will be :-
Hence, the value of the t‑statistic for this test : t= 0.866
