Question
For a one-tailed test (lower tail) with 22 degrees of freedom at 95% confidence, the value of t =Question 6Select one:a.1.383b.-1.721c.-1.383d.-1.717
Solution
The answer is d. -1.717.
Here's why:
A one-tailed test (lower tail) at 95% confidence with 22 degrees of freedom refers to the t-distribution table. The t-distribution table is used to find the critical value.
In this case, you are looking for the critical value in the lower tail (left side of the distribution curve) at 95% confidence level.
The degrees of freedom (df) is 22.
When you look up these values in the t-distribution table, you will find that the critical value is -1.717.
Therefore, the answer is d. -1.717.
