How do I find the p value? Please explain in detail

Previous Problem Problem List Next Problem 1 polnt) Here we Investigate whether the register balance at a local retail store is better on days with a manager than days without a manager. This evidence might be used to determine whether or not you should always schedule a manager. The table gives the register balance for a sample of 10 days with a manager and 10 days without a manager. Here, 0 means the register balance is right on, negative means there is less money than there should be, and positive means there is more money than there should be. The number of degrees of freedom (d.1.) that you should use in your calculations is glven in the table.
