i need help solving this problem

Complete the following steps for the hypothesis test. A local real estate company wanted to know if attending a course on "How to be a Successful Salesperson" can increase the weekly average sales (listed in thousands) of its employees. The company sent six of its salespersons to attend this course. Using a 1% significance level, can you conclude that the mean weekly sales for all salespersons as a result of attending this course has not changed? Assume that the population of paired differences has a normal distribution. Sales Before the $120 $180 $250 $90 $140 $160 Course Sales After $180 $240 $240 the Course $140 $190 $200 coutsos/3579/quizzes/83999/lake, 2/4 /2021 Quiz: Chapter 8 Section 4 - Homework Step 1: Write the hypothesis statements, identify which hypothesis is the claim, and the type of test you need to complete (left-, right-, two-tail). State the level of significance. . For "#" write "not equal". . For statements that are not the "claim", write "NA". in the box for claim. Ho : H 0 Claim ?: H1: / 0 Claim?: Tailed-Test: -tailed test Significance Level: a = Step 2: Check the requirements. Calculate the appropriate standardized test statistic (two decimal places) and P-value (4 decimal places). State the calculator function (Z-Test, T-Test, 1-PropZTest, 2-SampZTest, 2- Samp TTest). . Remember that two-tailed tests have two standardized test statistics, always state both. . Use the correct standard deviation variable, write NA in the remaining one. Calculator Function: Data/Stats?: Given being entered: Ho: List: Before - After HO Standardized Tests Statistic(s): P-value = Step 3: Conclusion (make a decision) - your conclusion must include supporting evidence. Conclusion: the Ho Supporting Evidence:
