Answer: C. 25
Step-by-step explanation:
Given : The average rat (of this strain) can learn to run this type of maze in a box without any special coloring : [tex]\mu=25[/tex]
The mean number of trials to learn the maze, for the rats tested with the colorful wallpaper= [tex]M= 11[/tex]
We know that the sampling distribution D is given by :-
[tex]\mu_D=\mu[/tex]
Similarly the mean of the distribution M in the given situation is given by :_
[tex]\mu_M=\mu=25[/tex]
The mean of the distribution M in the given situation is 25. Then the correct option is C.
It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.
An experimental psychologist is interested in whether the color of an animal's surroundings affects the learning rate.
He tests 16 rats in a box with colorful wallpaper.
The average rate (of this strain) can learn to run this type of maze in a box without any special coloring in an average of 25 trials, with a variance of 64, and a normal distribution.
The mean number of trials to learn the maze, for the rats tested with the colorful wallpaper, is 11.
We know that the sampling distribution D is given by
μD = μ
Similarly, the mean of the distribution M in the given situation is given by
μD = μ = 25
