Question two :light and thermal energy
I hope this helps you
A little bit I can do
Answer:
greater than 0.10
Explanation:
The null hypothesis is:
![H_{0} = 10.2](https://tex.z-dn.net/?f=H_%7B0%7D%20%3D%2010.2)
The alternate hypotesis is:
![H_{1} > 10.2](https://tex.z-dn.net/?f=H_%7B1%7D%20%3E%2010.2)
Our test statistic is:
![t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%7D)
In which X is the statistic,
is the mean,
is the standard deviation and n is the size of the sample.
We have that:
![t = 0.45](https://tex.z-dn.net/?f=t%20%3D%200.45)
We are testing if X is greater than 0.45, so our pvalue is 1 subtracted by the pvalue of z = t = 0.45.
z = 0.45 has a pvalue of 0.6736
1 - 0.6735 = 0.3264
So our pvalue is 0.3264, which is greater than 0.10.
So the correct answer is:
greater than 0.10
