![]() ![]() To make sure each arm was straight, in alignment with each other, or To measure the wingspan of each subject we had the subject stretch his/herĪrms out horizontally or as horizontal as possible.Were incorrect and affected the calculation of the proportion. When measuring the individuals forearm, we used our own judgment to determine.The one-sample T-test concluded that there is enough evidence to say the proportion is not 1.618, phi. We found the proportion of Forearm+Hand to forearm to be 1.715 which is within 6% error of the established value of 1.618. The one-sample T-test concluded that there is not enough evidence to say the proportion is not 1. We found the proportion of Height to Wingspan to be 1.023 which is within 2.3% error of the established value of 1. We conclude that there is enough evidence The p-value of 1.076E-10 is small enough for us to reject the hypothesis that the true meanīody proportion is 1.618. We conclude that there is not enough evidence The p-value of 0.079 is not small enough for us to reject the hypothesis that the true meanīody proportion is 1. ![]() H A: Body Proportion Forearm Hand/Forearm ≠ 1.618 H O: Body Proportion Forearm Hand/Forearm = 1.618 We can safely assume that 25 people is less than 10% of the human population. We assume the students were selected randomly. Random Sample and One-Sample T-testĮach individual's measurement was not dependent on another's. To further statistically analyze the calculated measurements, we performed a t-test to determine whether the proportions found were significantly different to the established values. Graphically the proportion of forearm+hand to forearm is represented by coefficient A on the proportional fit equation, y=A*x, shown on the forearm+hand vs forearm graph. To find the proportion of forearm+hand to forearm, we divided the forearm+hand of the person over their measured forearm. Graphically the proportion of height to wingspan is represented by coefficient A on the proportional fit equation, y=A*x, shown on the Wingspan vs Height graph. The proportion of wingspan to height is found by dividing the wingspan of the person over their measured height. ![]() It is also believed that the proportion of a person's forearm to their hand is in a ratio of 1.6. It was previously believed that the wingspan of a person is equal to the height of that same person. The data collected can be found here in excel format.
