The hypothesis test H0:μ1−μ2=3 H1:μ1−μ2≠3 is to be carried out for population 1 and 2 where σ1 and σ2 are not known. A random sample of 27 from population 1 has a mean of 78.3 and a standard deviation of 8.8. A random sample of 44 from population 2 has a standard deviation of 7.9. The test statistic was found to be tc=−0.53130. What was the mean of the sample from population 2? x¯2 =
