In an experiment, two different species of flowers were crossbred.The resulting 217 flowers from this crossbreeding experiment were categorized by the color of the flower and the stigma.The table provides the study results.

Flower Type	1: Magenta flower with Green stigma	2: Magenta flower with Red stigma	3: Red flower with Green stigma	4: Red flower with Red stigma
Observed # Flowers	115	49	32	21

According to genetic theory, the four resulting flower types should follow the ratio of 9:3:3:1, that is, flower types should follow the following population proportions of 0.5625, 0.1875, 0.1875, and 0.0625.The biologist is interested in assessing whether the distribution of flower type for the experiment matches these genetic theory rates.

State the null hypothesis for this test.
