Consider the following competing hypotheses and accompanying sample data drawn independently from normally distributedpopulations. (You may find it useful to reference the appropriate table: z table or ttable)HO: μ1HA: M1μ₂ = 0M2 < 0X1 = 242S1 = 25n1 = 8X2 = 269S2 19n2= 8Test statistic=a-1. Calculate the value of the test statistic under the assumption that the population variances are equal. (Negative value should beindicated by a minus sign. Round final answer to 3 decimal places.)

How does the variance of the sample mean compare to the variance of the population? Multiple Choice It is larger and therefore suggests that averages have more variation than individual observations. It is larger and therefore suggests that averages have less variation than individual observations. It is smaller and therefore suggests that averages have more variation than individual observations. It is smaller and therefore suggests thot averages have tess variation than individual obserVations. < Prev. 15 of 25 Next ere to search 18
