Question 14 (1 point) Find two different ways to state that two population means are equal for a null hypothesis in a 2-sample z-test. O HO: H1=a ; HO: p1 = b O HO: H1 = 12 ; HO: p1 = /42 O HO: H1 = 7; HO: H1 = 7 O HO: H1 = M2 ; HO: w1 - H2 =0Question 1? {1 point] The CEO of a large manufacturing company is curious if there is a difference in productivity level of her warehouse employees based on the region of the country the warehouse is located. She randomly selects 35 employees who work in warehouses on the East Coast lGroup 1] and 35 employees who work in warehouses in the Midwest [Group 2i and records the number of parts shipped out from each for a week. She finds that East l'Coast group ships an average of 128? parts and knows the population standard deviation to be 348. The Midwest group ships an average of 144'? parts and knows the population standard deviation to be 298. Using a 0.01 level of significance. test if there is a difference in productivity level. What are the correct hypotheses for this problem? OHD:p1= p2:H'l:p1#p2 OHD:plsp2;H1:p.1=zp2 OHD:p1=p2;H11u1=p2 OHD:p12p2;H1:p.lsp2 OHD:p1=p2;H1Lp.1=p2 OHD:p1}p2;H1:u1=p2
