Question 4 1 pts Cost and Customer Satisfaction A researcher is interested whether there is a linear correlation between cost (in dollars) of internet service per month and customer satisfaction on a scale of 1 - 10 (with a 1 being extremely dissatisfied and 10 extremely satisfied). The researcher only includes internet service with similar download speed. The sample he collected is below. Cost (x) 15 18 17 11 9 11 12 19 18 22 Satisfaction (y) 6 8 10 4 9 6 3 5 2 10 Find the value of the linear correlation coefficient r. Round your answer to 3 decimal places, if needed.Question 5 1 pts Cost and Customer Satisfaction A researcher is interested whether there is a linear correlation between cost (in dollars) of internet service per month and customer satisfaction on a scale of 1 - 10 (with a 1 being extremely dissatisfied and 10 extremely satisfied). The researcher only includes internet service with similar download speed. The sample he collected is below. Cost (x) 15 18 17 11 9 11 12 19 18 22 Satisfaction (y) 6 8 10 4 9 6 3 5 2 10 Find the regression equation. O y = 0.222 +0.149x O y= 0.149 + 4.03x O y = 4.03 + 0.222x O y = 4.03 + 0.149xQuestion 6 1 pts Cost and Customer Satisfaction A researcher is interested whether there is a linear correlation between cost (in dollars) of internet service per month and customer satisfaction on a scale of 1 - 10 (with a 1 being extremely dissatisfied and 10 extremely satisfied). The researcher only includes internet service with similar download speed. The sample he collected is below. Cost (x) 15 18 17 11 9 11 Satisfaction (y) 12 19 6 18 8 22 10 4 9 6 3 5 2 10 Find the best predicted value for the level of Customer Satisfaction given that the Cost is 13. Use a significance level of 0.05. Round your answer to 1 decimal place, if needed
