Answer:
The value of the test statistic and the number of degrees of freedom is 2.148 and 11 respectively.
Step-by-step explanation:
The mean annual tuition and fees for a sample of 12 private colleges was $36,800 with a standard deviation of $5000
n = 12
Claim: You wish to test whether the mean tuition and fees for private colleges is different from $33,700
Since n < 30 and sample standard deviation is given so, we will use t test
Formula :
Substitute the values in the formula :
Degree of freedom = n-1 = 12-1 =11
So,. Option D is true
Hence the value of the test statistic and the number of degrees of freedom is 2.148 and 11 respectively.
Answer: yes
explanation: yes
Answer:
The slope is -8
Step-by-step explanation:
To find the slope, we can do a very easy equation. We can do the formula
y1 - y2 / x1 - x2
We fit in all of the respective numbers to get the equation as this.
-51-(-75) / 7-10
Then, we get
24/ -3
Simple division gives us -8.
