Recently, a neurotransmitter called Galanin has been discovered that appears to effect one's desire to eat foods with a high fat content. Specifically, the more of this naturally occurring neurotransmitter an individual possesses, the higher his/her craving for high fat foods. Recently, a drug company developed an experimental drug that blocks Galanin without affecting appetite for lower fat foods. The company immediately sets out to test the drug. An experiment is conducted in which 12 female volunteers are randomly selected and given a daily dose of the experimental drug for six months. Their weights are measured before and after the drug treatment. The data from study are in the table below.Can the pharmaceutical company conclude that the mean weight after the drug is significantly different than mean weight before the administration of the drug?

Question

Recently, a neurotransmitter called Galanin has been discovered that appears to effect one's desire to eat foods with a high fat content. Specifically, the more of this naturally occurring neurotransmitter an individual possesses, the higher his/her craving for high fat foods. Recently, a drug company developed an experimental drug that blocks Galanin without affecting appetite for lower fat foods. The company immediately sets out to test the drug. An experiment is conducted in which 12 female volunteers are randomly selected and given a daily dose of the experimental drug for six months. Their weights are measured before and after the drug treatment. The data from study are in the table below.
1. 1. Can the pharmaceutical company conclude that the mean weight after the drug is significantly different than mean weight before the administration of the drug? Test with an α = 0.01.
  2. Calculate and interpret the effect size.
