Insurance companies commonly use 1000 miles as the mean number of miles a car is driven per month. One insurance company claims that the mean number of miles a car is driven per month is different from 1000 miles. The insurance company conducts a hypothesis test and fails to reject the null hypothesis. Assume that in reality, the mean number of miles a car is driven per month is 1100 miles. Was an error made

step-by-step explanation:

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
