PLS HELP!

An engineer working in a plant that mass produces construction frames intended to test the consistency of frame heights produced by the plant. The random samples of = 60.1 inches and size ni = 5000 and n2 = 2000 yielded x = 64. 9 inches. Previous quality tests performed by other engineers in the plant have shown that it is sufficient to let 0j = 2.1 inches and oj = 2.15 1 2 inches. Test at the 0.05 level of significance whether the difference between these two sample means is significantly different. Instructions: Assume 8 = 0, in addressing the problem obtain the value of the test statistic and its corresponding p – value up to four decimal places. 23D —85. 8033; р — value — 0. 0530 Ог3 —84. 9424; р — value = 0.0000 23 —85.8033;B р— value 0.0000 23D -84.9424; р — value 0.0530
