Question

Comparisons. please provide step-by-step explination

Hypothesis is that the proportion of American circus artists who are primarily aerialists is different than the proportion of Canadian circus artists who are primarily aerialists. I used my data from last week’s post, and collected new data, again using my Facebook friends list, for the second population sample.

Population 1 (American circus artists):

Sample size: 50

Yes: 23

Sample proportion: 0.46

Population 2 (Canadian circus artists):

Total: 50

Yes: 12

Sample proportion: 0.24

p₁ : proportion of successes for population 1

p₂ : proportion of successes for population 2

p₁ – p₂ : Difference in proportions

H₀ : p₁ – p₂ = 0

H_A : p₁ – p₂ ¹ 0
