Determine the null and alternative hypotheses. Choose the correct answer below.

Many dairy cows now receive injections of a hormone intended to spur greater milk production. After the first injection, a test herd of 58 random Breed A cows increased their mean daily production from 47 pounds to 60 pounds of milk. The standard deviation of the increases was 5.2 pounds. Additionally, a test group of 54 random Breed B cows increased average milk production from 43 pounds to 51 pounds per day, with a standard deviation of 4.8 pounds. Is this evidence that the hormone may be more effective in one breed than the other? Test an appropriate hypothesis and state an appropriate conclusion. Be sure to discuss any necessary assumptions. Determine the null and alternative hypotheses. Choose the correct answer below. OA. HO: HD #0 O B. HO: HA - HB = 0 HA: HD = 0 HA: HA - HB > 0 O C. HO: HD = 0 O D. HO: HA - HB = 0 HA: HD > 0 HA: HA - HB # 0 OE. HO: HA - HB = 0 OF. HO: HA - HB $ 0 HA: HA - HB
