What is the following value of the appropriate test statistic using excel? This is a practice quiz we went over with the professor. Trying to understand how it was solved in practice ### Sales Training Program Effectiveness Test#### Objective:A new sales training program has been instituted at a company aiming to enhance employees' knowledge of the products offered. To determine the program's effectiveness, a pretest and posttest were administered to a group of employees.#### Instructions:1. **Pretest Score** (\( \mu_1 \)): Score obtained by employees before undergoing the training program.2. **Posttest Score** (\( \mu_2 \)): Score obtained by the same employees after completing the training program.3. **Score Difference**: The difference is calculated as the pretest score minus the posttest score.The scores from the tests are listed in the table below:| Pretest Score | Posttest Score ||---------------|----------------|| 56 | 66 || 94 | 97 || 90 | 96 || 69 | 78 || 96 | 90 || 71 | 75 |**Question**:Which of the following is the value of the appropriate t?#### Explanation:The table above shows a comparison of pretest and posttest scores for six employees. The objective is to determine if there is a statistically significant difference between the pretest and posttest scores using a suitable statistical test, likely a paired t-test, to evaluate the training program's effectiveness.For educational purposes, students or analysts can calculate the differences between the pretest and posttest scores for each employee and then perform the t-test to check for significance. Calculating this will involve:1. Finding the difference for each pair (pretest score - posttest score).2. Calculating the mean difference.3. Determining the standard deviation of the differences.4. Using these values to compute the t-value.Students are encouraged to follow these steps accurately and refer to statistical tables or software to find the t-value and understand its significance level in the context of their hypothesis.**Note**: The specific value of "the appropriate t" will depend on the analysis performed using the scores provided.

Let the samples be taken randomly Here, each variable is used in the two samples hence the samples…

Aspirin prevents blood from clotting and helps prevent strokes. The Second European Stroke Prevention Study asked whether adding another anticlotting drug named dipyridamole would make a difference for patients who had already had a stroke. Here are the data on strokes during the two years of the study: Aspirin alone Apsirin & Dipyridamole Number of Patients This test is two-t led. What is the test statistic? -2.700 200 = V 200 Is there a significant difference in the proportion of strokes in the two groups? Test at a = 0.05. Round your answers to three decimal places, and round any interim calculations to four decimal places. #v Fill in the hypotheses below where p₁ denotes the proportion of patients in the aspirin group who suffered a stroke and på denotes the proportion of patients in the aspirin & dipyridamole group who suffered a stroke. Ho: P₁ Ha: P₁ Number of Strokes P₂ 60 P₂ 86 Using your answer from the previous question, find the p-value. ▼ Part 2 of 4 Part 3 of 4
