For Problems 14, state the nll hypothesis, the alternative hypothesis, the test statistic, the test {in the form \"the test rejects H0 if .-.\" ), and the pvalne- Determine Whether we accept or reject the null hypothesis based on both approaches: via the test itself and via the pvalue. Compute each numerical value to at least two digits after the decinlal point (more if necessary). Note that the pvalue can sometimes be verj.r large {c.g., > 0.5) or small (e.g., close to U), which just means that it is easy to make a decision. The viscosity of two different brands of car oil is measured, resulting in data for Brand 1: 10.62, 10.58, 10.33, 10.72, 10.44, 10.74; and data for Brand 2: 10.50, 10.52, 10.58, 10.62, 10.55, 10.51, 10.53. Test at significance level 0.01 the hypothesis that the mean viscosity of Brand 1 is equal to that of Brand 2, assuming that the populations have normal distributions with equal variances
