Please use the following formula for hypothesis test for the slope (b1) to answer the following question: A researcher wanted to determine whether years of experience play a significant role in increasing the salary of the employees. He collected a random sample of 10 employees having experience of 1 to 10 years and recorded their annual salary (in $). Determine whether years of experience and salary have a significant relationship or not. Years of experience Salary($) 1 40000 2 53000 3 60000 4 78000 5 110000 6 152000 7 200000 8 240000 9 255000 10 300000 Apply the test for significance of slope and check whether the relationship is significant or not.
