The germination rate of seeds is defined as the proportion of seeds that, when properly planted and watered, sprout and grow

The germination rate of seeds is defined as the proportion of seeds that, when properly planted and watered, sprout and grow. A certain variety of grass seed usually has a germination rate of 0.80, and a company wants to see if spraying the seeds with a chemical that is known to change germination rates in other species will change the germination rate of this grass species. They spray 400 seeds with the chemical, and 307 of the seeds germinate.This produces a 95% confidence interval for the proportion of seeds that germinate of (0.726,

0.809).

Use the confidence interval to draw a detailed conclusion about the hypothesis
