You find that the sample from Tampa showed anaverage salary of $56900 with a standard deviation of 6000, and the sample from Dallas showed an averagesalary of $61700 with a standard deviation of 6950.(Assume both populations are normally distributed, but you do not know the standard deviations for either.Also, you have no reason to believe the variances of the two populations are equal.)a. What is the test statistic for this sample?test statisticRound to 4 decimal places.b. What is the p-value for this sample?p-value =Round to 4 decimal places.%3Dc. The p-value is...O less than (or equal to) agreater than ad. This test statistic leads to a decision to...O reject the nullaccept the nullO fail to reject the nulle.
