Question

In a university it is generally said that the academic performance of the faculty A is lower than that of faculty B. The head of grades has been asked about the respective averages and standard deviations, and he only remembers the latter, 0.7 and 0.86 respectively. It is proposed to carry out a study with two samples of size 20 and 28 in each faculty, obtaining averages of 3.32 and 3.50. At the 5% level, can we accept what is generally said?
