Calculate the critical t-value(s) for each of the given hypothesis test scenarios below. If mulitple critical values exist for a single scenario, enter the solutions using a comma-separated list. Round t-values to four decimal places.

• Find the critical t-value(s) for a left-tailed test of hypothesis for a mean, assuming the population standard deviation is unknown, with a sample size of 25 and let α=0.005.
