Question

Problem 81

Answer 1

Given information

The average man’s I.Q.= 107; The average brown trout’s I.Q.= 4; the sample size(n)= 12; degree of freedom=12-1=11;

A fish psychologist determines the I.Q.s as follows: 5; 4; 7; 3; 6; 4; 5; 3; 6; 3; 8; 5.

Step-by-step explanation

Step 1.

Mean for the given hypothesis =(Sum of all the samples)/(total no. of samples);

=(5+4+7+3+6+4+5+3+6+3+8+5)/12=59/12;

=4.916;

Now, the standard deviation (s)= (s)=1.62;
