Question:

What is 45% of 70?

Kristina S.

Answer:

31.5. Using the cross-multiple method we would set up the following equation to solve for x: 45%/100% = x/70. Next we cross-multiple to get: 100x = 45*70 which simplifies to 100x = 3,150. Next we divide both sides by 100: x = 3,150/100. So x = 31.5.

Question:

Why is it importance to check that certain conditions are met before running a test of significance?

Kristina S.

Answer:

It is important to check the conditions for a test of significance because this will ensure that we are using the right procedures and will get accurate statistics and conclusions. If the conditions are not met and we still follow the same procedures, our answers will not be accurate and may even be contradictory to what the true conclusion should be.

Question:

What is the significance and purpose of constructing a confidence interval?

Kristina S.

Answer:

Confidence Intervals are important because we will generally never know the true value of a certain parameter for a given population. Confidence intervals allow us to fairly accurately estimate what the true value of a parameter would be based on sample data. We can create wider or narrower ranges for the parameter depending on what level of confidence we want to use.
