8)Psychology experiments sometimes involve testing the ability of rats to navigate a maze. One researcher needs a maze that will take rats an average of two minutes to solve. He tests several rats on a maze that he thinks will meet his needs. The data is shown below. Assume all conditions and assumptions have been met. Will this maze take the rats too little time? Use a significance level of ?=0.05.

in an experiment on learning 70 rats were taught to navigate a maze during a 3 week training period. half the rats (n=35) were randomly selected to receive cocaine injections for a week while the other half received sodium placebos. after the drug treatment the rats were then tested in the maze and their response times were recorded. for rats who received cocaine the sample mean was 16.83 seconds and ss= 903.04 for the rats who received the placebo the...

Related T-Test Sample 1. A researcher is interested in testing whether rats learned a maze after daily training sessions. The researcher recorded the number of errors committed by each rat before any training in the maze. Then, the researcher recorded the number of errors made by each rat after training. The scores below summarize the errors by each rat before and after training. Perform a dependent-sample (repeated-measures) t-test on the scores to test whether or not the number of errors...

Maze navigation ability is an indicator of cognitive performance in rats. Consider an experiment where some mice from a maze-bright strain are reared in a restricted environment (Group A) whereas others are reared in their normal environment (Group B) and answer the following questions. 1. If maze-navigation ability is only influenced by genetics, how would you expect the maze navigation performance of rats from Group A to compare with those from Group B? 2. If maze-navigation ability is affected by...

A researcher is investigating the effects of ambient noise on the ability of rats to learn to navigate a maze. A total of 10 rats were tested, half were randomly assigned to a no noise condition and the other half assigned to a loud ambient noise condition. For each rat, the researcher determined how many trials it took to run the maze without any errors. The results are summarized in the chart below. Rat # No Noise: Score No Noise:...

A researcher studies the role of the brain chemical serotonin in aggression. One sample of rats receives a placebo while another sample of rats receives a drug that lowers brain levels of serotonin. Then the researcher tests the animals by recording the number of aggressive responses each of the rats display. What statistical test could be used to analyze data from this study? a. Independent measures t-test b. Independent measures ANOVA c. Repeated measures t-test d. Both a and b

Scientist were testing how fast (seconds) 2 types of rats could race 5 m down one section of the brand-new shiny hallways of the new Biological sciences building at SHSU. However, these scientists are a bit stuck as the samples have clearly not been sampled from a normal distribution. Could you help them out with their statistics by running an appropriate t-test to see if Rat A was slower than Rat B? Course times (seconds) for Rat A: 6.43 6.99 6.43...
