The manager of Tile Central believes that the Virginia store is more profitable, in terms of weekly profit per full-time employee, than the Clayfield store. Random samples of size 15 and 10 accounting records for Virginia and Clayfield, respectively, were taken. These yielded average weekly profit per full-time employee results for Virginia and Clayfield of $296.44 and $273.50, respectively, and standard deviations of 30.07 and 27.02 dollars, respectively.It is assumed that the population variances are the same and weekly profit per full time employee for both stores is normally distributed. Considering Virginia store as population 1 and Clafield store as population 2, what is the critical value at the 10% level of significance (use our textbook statistical table to answer the question)?
