Answer:
The answer is in the explanation
Step-by-step explanation:
Mean value = = 438
(a) The data appeared to be centered towards 438.
There are little or no skew.
There is no outliers.
(b) yes
(c) standard deviation = s = 14.8955
95% confidence interval =
=
= (430.3415, 445.6585)
(d) Test statistic
t =
t = -3.3216
p -value is correctly given in option b.
No, 450 is not a plausible valaue.
So hmm check the picture below
so.. that means the interior angle at the vertex R is 180 - 82, or 98
now, the sum of all interior angles of a polygon is 180(n - 2)
where "n" is how many sides are there in the polygon
this is a pentagon, so 5 sides, so, the sum of all the interior angles is then
180( 5 - 2)
180(3)
540
that means that
98 + 82 + c + 116 + c = 540
2c + 98 + 82 + 116 = 540 <----- solve for "c"
