A sample of size 21 is taken and a significance test for H0 : u = 0 versus Ha : u doesnt equal 0 is run. The test statistic is t = 1.71. Use 3 decimal places for t values and 2 decimal places for p-values.
- What are the degrees of freedom for this statistic?
- Give the two values from the t-table that would appropriately bracket t = 1.71.
What is the lower limit for 1.71 in the t-table?
- What is the upper limit for 1.71 in the t-table?
- Give the right-tail probabilities for these two limits.
What is the right-tail probability for the lower limit, 1.325?
- What is the right-tail probability for the upper limit, 1.725?
- What is the upper limit for the p-value of the test?
- What is the lower limit for the p-value of the test?
