For conducting a two-tailed hypothesis test with a certain data set, using the smaller of n1minus−1 and n2minus−1 for the degrees of freedom results in df equals=11, and the corresponding critical values are tequals=plus or minus±2.201. Using the formula for the exact degrees of freedom results in drf equals=19.063, and the corresponding critical values are tequals=plus or minus±2.093. How is using the critical values of tequals=plus or minus±2.201 more "conservative" than using the critical values of plus or minus±2.093

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
