recessive?

Field Study on Recessive Traits
Learning Objective: LS: 3.1. Apply concept of statistics and
probability to explain the variation and distribution of expressed
traits in a population.
Hypothesis: Based on the students I see on a daily basis, specifically
talking about the different people in my classes, I had noticed there
was a least amount of people with cleft chins, then without. Therefore, concluding in my belief that having a cleft chin is a recessive trait.
In reasoning with my hypothesis, I picked a day to go around my high school, Rancho Mirage High School, to ask and observe 45 fellow students to see whether or not they carry the trait of a cleft chin. As a result, 34/45 students I had asked qualified of having the trait of no cleft chin. The rest of the eleven students carry the trait of a cleft chin.

DATA:
Hardy Weinberg Equation : q ^ 2 + 2pq + p ^ 2 = 1
q^2 -------------> 34/45 = .76
q---------> .76 = 0.87
p --------> 1 - .87 = 0.13
p^2 ---------> .13x .13 = 0.2
2pq--------> .87x. 13x2 = .22
Now, according to this data, the homozygous dominate is 2%,
heterozygous is 22% and homozygous recessive is 76%.
In conclusion, I now understand how to use the equation of Hardy Weinberg.
Also, know the dominant trait is no cleft chin, therefore, my hypothesis was correct.
heterozygous is 22% and homozygous recessive is 76%.
