Accu-Copiers, Inc., sells and services the Accu-500 copying machine. As part of its standard service contract, the company agrees to perform routine service on this copier. To obtain information about the time it takes to perform routine service, Accu-Copiers has collected data for 11 service calls. Which variable is the explanatory or predictor variable? Explain Create scatter plot in Excel and determine if there is a relationship in between variables. Can number of copiers predict service time? Run the regression Model in Excel. Copy and paste entire output below. Find the least squares point estimates b0 and b1 on the computer output and report their values. Interpret b0 and b1 in the problem context. Write down the regression equation. Does the interpretation of b0 make practical sense?

A researcher wonders if expression levels of genes and proteins are highly correlated or not. They measure expression levels of 10 genes and the proteins encoded by them. Then, Pearson correlation coefficient is calculated to be 0.75. Conduct a hypothesis test to decide if correlation of gene and protein expression is more than 0.4. Use a = 0.05.
