How to determine the test statistic and critical value for the test? A car manufacturer states that the fuel consumption of their new model is 5.4 litres per 100km. A sample of 36cars was tested and the average fuel consumption of the cars was found to be 7.0 litres per 100km. The standarddeviation of the sample was 2.1 litres per 100km. It is desired to determine whether there is sufficient evidence at a5% significance level to conclude that the fuel consumption is different from 5.4 litres per 100km.The hypotheses are given as:Ho : | = 5.4H₁: 5.4You are required to determine the test statistic and critical value for this test.

Given,sample size(n)=36sample mean(x¯)=7.0sample standard deviation(s)=2.1population…

Describe a situation where you would use a test of significance on the difference between the means of two populations by stating a pair of populations composed of the same type of individuals and a quantitative variable on those populations.

What is the null hypothesis? Why do we want to reject our null hypothesis? The first step is the find the mean of our sample and compare it to the "hypothesized" mean of our null hypothesis—why do we do that? We use the results of our first step to calculate a test-statistic. Why is this important and how does it relate to the concept of z-score, which we learned a few weeks ago? What is a p-value? What role does it play in the rejection of the null hypothesis? What does it mean to reject the null hypothesis? Does that guarantee that the null hypothesis is false?
