Listed below are the numbers of words spoken in a day by each member of eight different randomly selected couples. Complete part
s (a) and (b) below.
Male Female
16,051 24,017
26,378 12,962
1440 17,644
7875 17,399

15,728 16,581
14,306 16,533
26,823 18,967
a. Use a 0.05 significance level to test the claim that among couples, males speak fewer words in a day than females.
In this example, mu Subscript d is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the words spoken by the male minus words spoken by the female. What are the null and alternative hypotheses for the hypothesis test?
The test statistic is -0.35
The P-value is 0.369
What is the conclusion based on the hypothesis test?

Answer: yes it can be a measure of a triangle
I hoped i helped you and can i have brainliest if it's ok? ty
Sides: a = 6 b = 11 c = 13
Area: T = 32.863
Perimeter: p = 30
Semiperimeter: s = 15
As here we are given with an equilateral triangle, whose side is 3 cm, and we need to find the height and area of the equilateral triangle. So, for this let's recall that, the area of any equilateral triangle with side a is given by ;
So, if we substitute a = 3, in our Formula, it will yield to
Now, as we know that, for any triangle we also have a formula that is ;
Now, Here as the triangle is equilateral, so it's base will just be same 3, and if we let height be H, so we will be having
