Due to recent trends in the childcare industry,the firm suspects that the mean annual income of childcare workers in Texas is less than the mean annual income of childcare workers in Indiana. To see if thisis true, the firm selected a random sample of 10 childcare workers from Texas and an independent random sample of 10 childcare workers from Indiana andasked them to report their mean annual income. The data obtained were as follows.Annual income in dollarsTexas 35102, 40287, 32854, 29080, 36394, 22024, 22493, 31602, 27434, 40040Indiana 38446, 33018, 38027, 43504, 37962, 33838, 35730, 36793, 37714, 25715HD 144HzSend data to calculator VThe population standard deviation for the annual incomes of childcare workers in Texas and in Indiana are estimated as 6200 and 6500, respectively.
