The t procedure can be used when the sample size of each group is at least 15 or when the sample sizes are between 10 and 15 and the data is reasonably close to normal. Therefore, the total sample size should be at least 30 (15+15) for the t procedure to be used. Choice C specifies a range of sample sizes that meets this criterion.
