Which of the following statements are true concerning the mean of the differences between two dependent samples (matched pairs)? Select all that apply. O A. The requirement of a simple random sample is satisfied if we have matched pairs of convenience sampling data. O B. If one has twenty-five matched pairs of sample data, there is a loose requirement that the twenty-five differences appear to be from a normally distributed population. O C. The methods used to evaluate the mean of the differences between two dependent variables apply if one has 92 IQ scores of men from New York and 92 IQ scores of men from California. O D. If one wants to use a confidence interval to test the claim that µg > 0 with a 0.10 significance level, the confidence interval should have a confidence level of 80%. D E. If one has more than 2 matched pairs of sample data, one can consider the sample to be large and there is no need to check for normality.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
