Dr. Stambaugh hypothesizes that a novel anxiety drug will affect memory. To examine this, the drug is administered to a random sample of 31 trained rats. The rats were then placed in a maze and timed on how long it took them to complete it. The average completion time was 51 seconds. Normal rats have an average completion time of 45 seconds with a standard deviation of 12 seconds. What can Dr. Stambaugh conclude with α = 0.01? a) What...
Dr. Stambaugh hypothesizes that a novel anxiety drug will affect memory. To examine this, the drug is administered to a random sample of 23 trained rats. The rats were then placed in a maze and timed on how long it took them to complete it. The average completion time was 47 seconds. Normal rats have an average completion time of 44 seconds with a standard deviation of 14 seconds. What can Dr. Stambaugh conclude with α = 0.01? a) State...
A health psychologist working a in nursing home believes that personal control is associated with feelings of well-being. In a field experiment, residents on one floor of the nursing home were given opportunities for personal control in their lives; e.g., arrange their own furniture, decide how to spend free time, choose and take care of a plant, etc. In another floor, residents were treated as usual. After a month the residents are asked to fill out a feelings of well-being...
