Find the critical value t for the confidence level c= 0.98 and sample size n=7.
1 answer:
Answer:
The critical value is T = 3.143.
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 7 - 1 = 6
98% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 6 degrees of freedom(y-axis) and a confidence level of . So we have T = 3.143.
The critical value is T = 3.143.

Bobby is right, because at x = -2, 3, and 5, the denominator of the function equals zero, which is by definition undefined.
