A researcher hypothesizes that electrical stimulation of a region of the ventromedial hypothalamus will result in appetite suppression. To test this, one set of rats is given electrical stimulation, while a control group does not. Rats are subsequently given unrestricted access to sugar pellets for 5 minutes, and the number of pellets eaten is recorded.

a. Use the appropriate test of hypothesis to determine whether or not the treatment rats consume fewer pellets. Use α = .05

No Stimulation: 12, 7, 3, 11, 8,5,14,7,9,10
Stimulation: 8,7,4,14,6,7,12,5,5

b. Based on these findings, what is the exact probability of a Type 1 error occurring?

Solutions

Expert Solution

type 1 error = reject H0 when H0 is true.

probability of type 1 error = alpha .

. Electrical stimulation is applied to entorhinal cortex, and neural recording is made at the output of hippocampus. After repeatedly applying stimulation, it is found that synapses at the recording site did not change in any way (i.e., did not show greater activity when activated). Explain why change in synaptic activity did not occur, and suggest what occurred at the level of the synapse. Describe all relevant events.

Under certain conditions, electrical stimulation of a beef carcass will improve the tenderness of the meat. In one study of this effect, beef carcasses were split in half; one side (half) was subjected to a brief electrical current and the other side was an untreated control. For each side, a steak was cut and tested in various ways for tenderness. In one test, the experimenter obtained a specimen of connective tissue (collagen) from the steak and determined the temperature at...

To test this, the researcher carefully controls for exercise while comparing the cholesterol levels of a group of subjects who lose weight by dieting with a control group that does not diet. f) Suppose a study was conducted on the effectiveness of a class on "How to take tests."

A researcher hypothesizes that caffeine will affect the speed with which people read. To test this, the researcher randomly assigns 8 people into one of two groups: 50mg Caffeine (n1 = 4) or No Caffeine (n2 = 4). An hour after the treatment, the 8 participants in the study are asked to read from a book for 1 minute; the researcher counts the number of words each participant finished reading. The following are the data for each sample: 50mg Caffeine...

A researcher hypothesizes that a pleasant distraction will change tolerance of a painful stimulus. 10 volunteers are exposed to experimental conditions: pleasant imagery (e.g., walking on the beach in Hawaii) vs. no instructions (the control condition). Each participant experiences both conditions. During each condition, participants perform the cold-pressor task. On this task, the participant sticks his/her arm in a bucket of freezing cold water. The dependent measure is how long the individual can keep his/her arm in before pulling it...
