Answer: 14
Step-by-step explanation:
- Degrees of freedom is the number of values in the evaluation of a test statistic that are free to vary.
For t-statistic , the degree of freedom for a sample with sample size 'n' is given by :-

Given : Sample size : n-1
Then, the number of degrees of freedom the t-value will have :-

Hence, the t-value will have 14 degrees of freedom.
Answer:
s=6
Step-by-step explanation:
slope(m) = (y2-y1)/(x2-x1)
or, -3 = (-6+9)/(5-s)
or, -3(5-s) = 3
or, -15+3s = 3
or, 3s = 18
so, s = 6
