Question

Maureen McIlvoy, owner and CEO of a mail order business for wind surfing equipment and supplies, is reviewing the order filling operations at her warehouses. Her goal is 100% of orders shipped within 24 hours. In previous years, neither warehouse has achieved the goal, but the East Coast Warehouse has consistently out-performed the West Coast Warehouse. Her staff randomly selected 200 orders from the West Coast Warehouse (population 1) and 400 orders from the East Coast Warehouse (population 2), and reports that 190 of the West Coast Orders were shipped within 24 hours, and the East Coast Warehouse shipped 372 orders within 24 hours. Assuming α = 0.05, the appropriate decision is ..

do not reject the null hypothesis μ₁ – μ₂ = 0

do not reject the null hypothesis p1 – p2 = 0

reject the null hypothesis μ1 – μ2 = 0

reject the null hypothesis p1 – p2 = 0

do not reject the null hypothesis p1 – p2 ≥ 0

Answer 1

I HOPE I WAS HELPFUL AND HAVE CLEARED YOUR DOUBTS.
