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)

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.
Answer:
Cube 1: 3375 cubed inches, 1350 inches squared.
Cube 2: 512 cubed inches, 384 inches squared.
Step-by-step explanation:
Formula for Volume of a Cube: (s - side length)
Formula for Surface Area of a Cube: (s- side length)
The side length's 15 inches.
Find the volume:
The volume of cube one is 3375in³.
Find the surface area:
The surface area of cube 1 is 1350in².
<h3>For Cube 2:</h3>The side length's 8 inches.
Find the volume:
The volume of cube two is 512in³.
Find the surface area:
The surface area of cube 2 is 384in².
