Costs for this service over the past eight months are as follows: \fRefer to the information for Luisa Crimini above. Required: Prepare a scatter graph based on Luisa's data. Use cost for the vertical axis and number of spray- tanning appointments for the horizontal. Based on an examination of the scatter graph, does there appear to be a linear relationship between the cost of spray-tanning services and the number of appointments?Refer to the information for Luisa Crimini above. Required: 1. Using a computer spreadsheet program such as Excel, run a regression on these data. Based on the regression output, write the cost formula for spray-tanning. (Note: Round the fixed cost to the nearest dollar and the variable rate to the nearest cent.) 2. Using the formula computed in requirement 1, what is the predicted cost of spray-tanning services for September for 2500 appointments
