When using a two sample test of means with equal standard deviations, then T distribution is the best option for it.

Sample test:

Sample test refers a method of reaching a conclusion to reject or support the claims based on sample data.

Given,

Here we need to identify in which  of the following are assumptions made when using a two sample test of means with equal standard deviations.

While we looking into the options for this one, then we have identified that, the sampling distribution of the difference of means is a T distribution.

So, the populations have equal but unknown standard deviation's.

Therefore, we "pool" the sample standard deviation.

What is the measure of KPN?
Debora [2.8K]

Answer:

angle KPN=95 degree

Step-by-step explanation:

angle KPN = angle JPO (because they are vertically opposite angles)

Now,

angle JPO+angle LOP=180 degree(being co interior angles)

angle JPO + 85 =180

angle JPO =180-85

angle JPO =95

since angle JPO is equal to KPN ,angle KPN is 95 degree

Which of the following statements is true
Tresset [83]
Hello There!

The first statement is incorrect as congruent angles have the same measure but it doesn't have to 45°. It can be any value.
The second one is also incorrect. Congruent angles have the same measure but don't always total to 180° (which is what supplementary means). It would only be true if they are congruent right angles.
The third one is also incorrect as they don't always total to 90° either (Which is what complementary means). 
The fourth one is correct, this is because congruent angles are simply angles with the same measure.

In short, you're answer is 4. Congruent angles always have the same measure. 


Hope This Helps You!
Good Luck :)

Solve y = x^2 +11 <br> for x.
lisabon 2012 [21]

Answer:

x = ± \sqrt{y-11}

Step-by-step explanation:

Given

y = x² + 11 ( subtract 11 from both sides )

y - 11 = x² ( take the square root of both sides )

± \sqrt{y-11} = \sqrt{x^2}, hence

x = ± \sqrt{y-11}
