2. Conduct a one-tailed hypothesis test, with a = .05. Identify the critical t value from the t table. 1 point The critical t value for a one talled hypothesis test with alpha equal to 0.05 would be 1.833. I found this on the t table, using the alpha value .05 and 9 degrees of freedom. I got 9 df because the number of data points is 10, and df is N (which is 10) minus 1. The value is here on the chart.
