Please help! My excel is not working! Thank you for your time!

'l". Enter the data into Excel. and create an KY plot of live. t. 3. Create a column in the spreadsheet calculating mm and create an X'r' plot of mm ys. t. Generate a linear trend line through this data. and record the slope ot that regression in Data Table 2. 9. Using the slope from your linear regression and your measured resistance, calculate the actual capacitance of the capacitor. Determine the percent error from the stated capacitance of 220 pF using the following formula: C [1.00922 F sou-1122 F I 100% Record your calculation in Data Table 2. Observations Data Table 1.
