Please answer the following. You may use excel for the computation although I suggest thatyou solve problem no. 4 manually. You can still use the manual computation if you havedifficulty of using the Excel. You may compute manually the mean and standard deviationand follow the examples in the lecture to do the step by step process of hypothesis testing.1. The grades of college Freshmen selected at random enrolled in College Algebra using 2different methods of teaching namely Traditional and Computer Aided Instruction, are asfollows:TraditionalComputer Aided Instruction2.01.252.751.51.51.752.252.02.51.751.52.02.251.251.501.51.751.752.51.252.5Determine if there is a significant difference in the grades of the students resultingfrom the use of two different methods of teaching at .05 level of significance.

Let's talk that scenario and work with some fictional data from it: Let's imagine there was a question on the survey that asks "On average, how many times a day do you worry about COVID-19, either for yourself, family, or community? Below is some data for 10 respondents. In the space below,describe all of the steps you would use to calculate the appropriate type of t-test (independent or paired samples), given we want to compare Trump voters to Clinton voters. For this question, just list the steps - do not do any calculations. That will be in the next question. Your list will have at least 6 steps. Just get as far as the t-statistic; no need to describe hypothesis testing steps in this problem.
