Answer:
A t-score of 2.0244 should be used to find the 99% confidence interval for the population mean
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 = 39 - 1 = 38
Now, we have to find a value of T, which is found looking at the t table, with 38 degrees of freedom(y-axis) and a confidence level of 0.99(). So we have T = 2.0244.
A t-score of 2.0244 should be used to find the 99% confidence interval for the population mean
Answer:
The answer is 2
Step-by-step explanation:
Rate of change of function is given by :
For function y = 6,
rate of change =
because the function is independent of x.
For function y = 2·x + 7,
rate of change =
So, the rate of change of 2 is greater than rate of change of function 1 by 2 - 0 = 2.
