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 sample mean was 10.60 seconds and ss=380.46

a) what is the tables value of the t statistic at the .05 level

b) what is the calculated value of the t statistic

c) is the null hypothesis accepted or rejected at the .05 level

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. Time (seconds) 113.4 122.2 110.5 125.0...

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...

Different breeding lines of rats ran a maze, then were exposed to an EMP (electro magnetic pulse, such as would occur from a nuclear explosion then ran a similar maze again. The maze running times were compared and the rats were classified into 3 groups. After slower than before, after close to before, and after faster than before. The categories are shown in the table below. Are different broads reacting differently to radiation? Test at the .01 level. Breeding line...

We have created a scientific experiment where one class of 40 people were taught using a flipped classroom. This class had an average score of 85. Also, we have observed from similar classes that σ = 3. We would like to test whether or not a flipped classroom improves the average grade compared to the standard class room’s mean grade of 84 with a standard deviation of 4. No students were in both the standard and flipped classrooms. 9. What...

1) During this distillation experiment, a student collects a 10.00 mL fraction consisting of 70% ethyl acetate and 30% n-butyl acetate (by volume). What is the mole fraction of n-butyl acetate in this sample? 2) Suppose you used a shorter distilling column in this fractional distillation experiment. Would you expect to obtain a better or worse separation between the two esters explain your answer.
