Answer:
Step-by-step explanation:
Given that A perfume company claims that the mean weight of ther new perfume is at least 8.9 fluid oz
For testing this claim, in Statistics we perform a certain measures called hypothesis testing.
For this first step is to create null and alternate hypothesis.
Normally null hypothesis would have some statistic = something
Here we want to test the mean weight of perfume
Hence null hypothesis would be
H0: mu = 8.9 fl oz.
Alternate hypothesis would be opposite of this claim
i.e.
Ha: mu ≠8.9 fluid oz
Hence answer is
Answer:
1428
Step-by-step explanation:
We first find the surface area of the triangle=base times height/2
height=8
We add 15+6=21, 21 times 8=168/2=84
We have 84 for this triangle, so the other triangle's area would also be 84
Now we find the area of the rectangle on the bottom-30 times 15=450
We then find the area of the other rectangle on the right side of the prism=30 times 17=510
Finally the area of the left-side of the prism=30 times 10=300
For the surface area, we add these all up=84+84+450+510+300=1428
Answer:
An experimental study because it will give the most accurate results.
Step-by-step explanation:
The observational study could also be somewhat useful, but the most accurate results will come from an experimental study. You will test the difference in DNA, blood pressure, and such. Whilst, the observational study, you only can observe the effects from the outside. The sample studies mean nothing because you can't test both sides of the complete study.
