- Which are the steps involved in the construction of explanatory bivariate tables?A pooled variance estimate is useful for two-sample hypothesis tests of a normal mean when the underlying population variances can be considered equal. True or False?Suppose a sample 30 observations is drawn from a population with variance population with variance population is 4.55 and the sample variance is 6.7. Test the hypothesis that the sample comes from a population with a variance greater than 4.55 at a 5% level of significance.
