Question

(e) The average depth of bedrock at two possible construction sites is to be compared by driving piles at five random locations at each site. The results, with depths in feet, are as follows. Paired t test or 2 sample t test??? please

Answer 1

Well, there isn't really pairs of data here; we have two samples of 5 data points
So we won't use a paired t test
Since we have two samples, we would use a two sample t test
