Try to explain first in English what you are doing, before jumping into formulas. For example “Next, I will calculate the cofactors of each element of the coefficient matrix”, “I will expand the determinant by the third row”, etc.... You are answers should be in ONE PDF file (that is ONE file, and it is not a JPG, HEIC or whatever other format).

Math 193 Exam, include sections 11.5-11.10, 10.1-10.2. Questions are followed in PDF. There are 13 questions in total.

Competency Formulate and evaluate hypothesis tests for population parameters based on sample statistics using both Critical Regions and P-Values, and be able to state results in a non-technical way that can be understood by consumers of the data instead of statisticians. Dealing with Two Populations Inferential statistics involves forming conclusions about a population parameter. We do so by constructing confidence intervals and testing claims about a population mean and other statistics. Typically, these methods deal with a sample from one population. We can extend the methods to situations involving two populations (and there are many such applications). This deliverable looks at two scenarios. Concept being Studied Your focus is on hypothesis tests and confidence intervals for two populations using two samples, some of which are independent and some of which are dependent. These concepts are an extension of hypothesis testing and confidence intervals which use statistics from one sample to make conclusions about population parameters. What to Submit Your research and analysis should be presented on the spreadsheet provided below.
