You are an analysis for a hot chocolate company, and want to investigate how weekly product sales are impacted by the current temperature. You investigate weekly sales data and average temperature for a particular region of customers over 77 weeks. You create a linear regression model to predict weekly sales. The model has residual standard deviation (8) of 3380 and a 8 of 6.5. The regression slope you get in your model is 109. Using this information, create a hypothesis test to investigate if the population regression slope of your model is not equal to zero. What is the value of the test statistic of your analysis? Note: 1-Only round your final answer. Round your final answer to two decimal places. Your Answer: Answer
