Answer: a) critical value = 0.0853, b) we reject the null hypothesis.
Step-by-step explanation:
Since we have given that
z = -1.37
And the hypothesis are given below:
Since α = 0.01
since critical value = 0.0853
As we can see that 0.853 < 0.25.
so, we reject the null hypothesis.
Hence, a) critical value = 0.0853, b) we reject the null hypothesis.
<h3>Answer: 1260 degrees</h3>
Explanation:
There are n = 9 sides to this polygon. Plug this value of n into the formula below to find the sum of the interior angles.
S = 180(n-2)
S = 180(9-2)
S = 180*7
S = 1260
