Jorge wants to create a model to predict sales (in $10000) based on the number of hours worked and the number of customers seen.Using the data below answer the questions:

Sales Hours Worked Number of Customers

15.64454

15.74352

15.44155

14.34155

11.84039

9.74028

9.64037

10.23858

11.33867

14.332186

In order to test if hours worked is a significant predictor of Sales given Number of customers is held constant, I would use the ___ test(Enter t, z,or p)

The p-value for the test statistic above (that is the test statistic to determine if hours worked is a significant predictor of Sales given Number of customers is held constant is ________ (write p-value to three significant digits)

Approximately 86% of the variability in Sales can be explained by the variability in hours worked (true or false)

To the nearest dollar (do not use dollar sign or comma), if a salesperson worked 40 hours and had 60 customers, what would you expect sales to be?

Is the residual for the last observation (the one with 32 hours worked and 186 customers) positive or negative (write positive or negative)
