Problem 15.4.6 from the collection of Kepe O.?. refers to the field of mathematical statistics and consists of the following: it is required to solve the problem of testing the hypothesis about the equality of mathematical expectations in two general populations with unknown but equal variances. The problem gives sample means and sample sizes from two groups, as well as a significance level. The solution to the problem is to find the critical value of the criterion statistic and compare it with the calculated statistic value. If the calculated value of the statistic falls into the critical region, then the hypothesis about the equality of mathematical expectations is rejected, otherwise the hypothesis is not rejected. Solving the problem includes calculations, construction of appropriate graphs and evaluation of the results obtained.
