We have provided summary statistics for independent simple random samples from two populations. In each case, use the non-pooled t-test and the non-pooled t-interval procedure to conduct the required hypothesis test and obtain the specified confidence interval. $$\bar{x}_{1}=10, s_{1}=2, n_{1}=15, \bar{x}_{2}=12, s_{2}=5, n_{2}=15$$ a. Two-tailed test, $\alpha=0.05$ b. $95 \%$ confidence interval
