DA1 Problem 3: Construct a 95% confidence interval estimating the difference between means for both problem 1 and problem 2 and interpret each confidence interval. Comparing the two confidence intervals, what do you notice? This problem is one of four problems in the data analysis assignment. It cannot be answered without the answers to Problems one and two. I am not able to upload a CSV/Excel file, it doesn't allow me to do so. I have included screenshots of the Data Needed to solve Problems one and two, which are needed to solve Problem three. I also included a screenshot of problems one and two to make sure you're able to answer those as well. I only want assistance with Problem 3. Please don't reject my request, I have given all the data necessary to help with answering the question.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
