Answer: ![9.465\times 10^{15}\ m](https://tex.z-dn.net/?f=9.465%5Ctimes%2010%5E%7B15%7D%5C%20m)
Step-by-step explanation:
Given
Seconds in a year is ![3.155\times 10^7](https://tex.z-dn.net/?f=3.155%5Ctimes%2010%5E7)
We know
![Distance=speed\times time](https://tex.z-dn.net/?f=Distance%3Dspeed%5Ctimes%20time%20)
Speed of light in vacuum is ![3\times 10^8\ m/s](https://tex.z-dn.net/?f=3%5Ctimes%2010%5E8%5C%20m%2Fs)
So distance traveled ![=3\times 10^8\times 3.155\times 10^7](https://tex.z-dn.net/?f=%3D3%5Ctimes%2010%5E8%5Ctimes%203.155%5Ctimes%2010%5E7)
![distance=9.465\times 10^{15}\ m](https://tex.z-dn.net/?f=distance%3D9.465%5Ctimes%2010%5E%7B15%7D%5C%20m)
Answer:
a) 13.277
Step-by-step explanation:
The chi-square critical value can be assessed using chi-square area table and for this table need value of alpha and degree of freedom.
The value of alpha is given which is 0.01 and degree of freedom can be calculated as
df=k-1
Where k represent the categories which are 5 in the given case.
df=5-1=4.
For alpha=0.01 and df=4, we get the chi-square critical value 13.277.
