What is the critical value for a one-tailed hypothesis test in which a null hypothesis is tested at the 5% level of significance based on two samples, both sample sizes are 13? The standard deviations for the samples are 5 and 7. Assume the population standard deviations are unequal. Please explain and show your work. Thank you!
