Answer:
Step-by-step explanation:
Given that evolution theory hypothesizes that people should spontaneously follow a 24-hour cycle of sleeping and wakingdash–even if they are not exposed to the usual pattern of sunlight.
Sample size n = 8
df = 8- 1=7
Since population std deviation is not known, and sample size is small we can use only t test
(two tailed test at 5% level of significance)

mean 25
sd 3.142857143
se 1.111167799
Test statistic = Mean diff/se = 1.595
p = 0.1546
since p >0.05, accept null hypothesis.
There is no evidence to prove that the steady cycle is different from 24 hours.

Step-by-step explanation:
we know that
The sum of the interior angles in any polygon is given by the formula
where
n is the number of sides of the polygon
step 1
Find the sum of the interior angles in the given polygon
we have
substitute
step 2
Find the value of x
we know that
solve for x
