Answer:
The critical value for this case can be calculated using the t distribution with 7 degrees of freedom and the critical value would be a value who accumulates 0.1 of the area in the right of the distribution and the best decision based on the possible options would be:
c). Reject H0 if test statistic is greater than 1.895.
Step-by-step explanation:
The system of hypothesis for this case are:
Null hypothesis:
Alternative hypothesis:
The statistic for this case is given by:
The degrees of freedom are given by:
The p value for this case can be calculated from this probability:
The critical value for this case can be calculated using the t distribution with 7 degrees of freedom and the critical value would be a value who accumulates 0.1 of the area in the right of the distribution and the best decision based on the possible options would be:
c). Reject H0 if test statistic is greater than 1.895.
I believe it is a because I had a question just like that in 8th grade
Given:
The expression is:
![2b^3+5](https://tex.z-dn.net/?f=2b%5E3%2B5)
To find:
The value of the given expression when
.
Solution:
We have,
![2b^3+5](https://tex.z-dn.net/?f=2b%5E3%2B5)
Substituting
in the above expression, we get
![2b^3+5=2(3)^3+5](https://tex.z-dn.net/?f=2b%5E3%2B5%3D2%283%29%5E3%2B5)
![2b^3+5=2(27)+5](https://tex.z-dn.net/?f=2b%5E3%2B5%3D2%2827%29%2B5)
![2b^3+5=54+5](https://tex.z-dn.net/?f=2b%5E3%2B5%3D54%2B5)
![2b^3+5=59](https://tex.z-dn.net/?f=2b%5E3%2B5%3D59)
Therefore, the value of given expression at
is 59.
