Question

Kara is supposed to have a learning percentage of 90 . Times for the first four units were 46.52,46.70,59.90, and 48.90 minutes. Does a learning percentage of 90 seem reasonable? Justify your answer using appropriate calculations. Although this question is subjective, in general consider learning rate estimates within +/−3% of Kara's target rate to be reasonable evidence that her target rate is true.

Answer 1

Kara's learning percentage of 90 does not seem reasonable based on the given times for the first four units.

Step-by-step explanation:

To determine if a learning percentage of 90 for Kara seems reasonable, we need to calculate her actual learning percentage based on the times for the first four units. The total time for the four units is 46.52 + 46.70 + 59.90 + 48.90 = 202.02 minutes. To calculate the learning percentage, we divide the total time by the target time and multiply by 100: (202.02 / 240) x 100 = 84.17%. Since Kara's learning percentage is lower than the target rate of 90, it does not seem reasonable based on these calculations.
