Kathryn, a golfer, has a sample driving distance mean of 187.3 yards from 13 drives. kathryn still claims that her average driving distance is 207 yards, and the low average can be attributed to chance. at the 1% significance level, does the data provide sufficient evidence to conclude that kathryn's mean driving distance is less than 207 yards? given the sample data below, accept or reject the hypothesis.

 1) D

2) C

Step-by-step explanation:

1. The blue algae has an initial mass of 20 kg and doubles its mass every hour. Then after t hours, the mass of blue algae is

2. The green algae has an initial mass of 160 kg and grows at a constant rate of 0.20 kg per minute. Then after t hours (60t minutes), the mass of green algae is

Part I) At t=3:

The mass of green algae has 196-160=36 kg more mass at 3 hours.

Part II) At t=4:

The blue algae has 320-208=112 kg more mass at 4 hours.
