The mean number of catfish caught daily at Lake Martin is 85, with the number of catfish ranging from 75 to 140. The mean number of catfish caught daily at Smith Lake is 104, with the number of catfish ranging from 96 to 183.

Write a statement that BEST compares the average values of the number of fish caught at both lakes daily.

There is a significant difference between the means of the two population

Step-by-step explanation:

The mean number of catfish caught daily at Lake Martin is 85, with the number of catfish ranging from 75 to 140.

Range = 140 - 75 = 65

The mean number of catfish caught daily at Smith Lake is 104, with the number of catfish ranging from 96 to 183.

Range = 183 - 96 = 87

Difference in mean = 104 - 85 = 19

If the confidence interval includes 0 we can say that there is no significant difference between the means of the two populations, at a given level of confidence

But by considering the mean difference and the value of range, we can say that

There is significant difference between the means of the two population

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
