A social geographer wants to know whether the mean length of unemployment differs among the residents of two local communities. Random sampling was performed, and records from each sample produced the following statistics: Statistic Town 1 Town 2 Sample size 52 62 Sample mean 3.4 months 2.8 months Sample standard deviation 1.1 months 0.8 months A test for equality of variances is performed, and it indicates that the two populations do not have equal variances. Based on this assumption, calculate the standard error of the sampling distribution of means. Match the statistical term with its correct value for this example. 1. test statistic, t* = 3.27 2. Assuming 51 degrees of freedom, what is the p-value associated with 0.002 the test statistic? 0.1833 3. The standard error of the sampling distribution of means is_
