Considering a factory with a production rate of 150 toys per hour, and taking into account possible fluctuations in the production speed, determine the estimated number of toys that the factory will manufacture during an 8-hour working shift.

Step 1: Determine the average production rate per hour
The factory has a production rate of 150 toys per hour. However, there might be fluctuations in the production speed. To account for these fluctuations, let's assume the production rate could vary by 10%. 

Step 2: Calculate the range of possible production rates
To find the range of possible production rates, we'll calculate 10% of 150 toys per hour and then add and subtract that amount from the average production rate.

10% of 150 toys per hour = 0.10 * 150 = 15 toys per hour

Lower limit of production rate = 150 - 15 = 135 toys per hour
Upper limit of production rate = 150 + 15 = 165 toys per hour

Step 3: Calculate the estimated number of toys produced during an 8-hour working shift
To find the estimated number of toys produced during an 8-hour working shift, we'll take the average of the lower and upper limits of the production rate and multiply it by the number of hours in the shift.

Average production rate = (135 + 165) / 2 = 300 / 2 = 150 toys per hour

Estimated number of toys produced during an 8-hour working shift = 150 toys per hour * 8 hours = 1200 toys. 

So, the factory will manufacture an estimated 1200 toys during an 8-hour working shift.
