Use the following information for the next few questions:

Ho: mu1 = mu2

H1: mu1=\=mu2

n1=12 and n2=11

alpha = 0.05

The critical value limits of Welch's t-test are (_________) and (upper) based on the textbook recommended simple way of determining the degrees of freedom. Record only the lower limit to three decimal places (example, 0.123).

Using the information from the previous question the null hypothesis should be rejected if t-value = 1.99?
