A hypothesis test procedure uses independent simple random samples to compare two unknown population means. The samples each have sample size 35, and yield the following sample statistics: x₁ =27.6, x2 =23.6, s1 =3.7, s2 =10.0, sd = 7.2 Compute the test statistic for the following null and alternative hypotheses. Use two decimal place accuracy. H₁ : µ1 = µ2 HA: M1 M2
