Jordan is chopping wood for the winter. for 10 days in a row, he follows the same process: in the morning, he chops 20 pieces of wood and in the afternoon, he chops an additional 30 pieces of wood. on the 11th day, jordan only chops 5 pieces of wood

The time would be 3.28 hours for a z-score of -1.2.

To find the time, all we need to do is use the equation for the z-score. Then, enter all the values we know and solve for the missing time.

Our equation is:

(Time - Mean) / Standard Deviation = z-Score

(x - 4.6) / 1.1 = -1.2
x - 4.6 = -1.32
x = 3.28 hours
