In a recent census, the proportions for these four ethnic groups are 0.177, 0.030, 0.734, and 0.059, respectively. Does the data suggest that the proportions in commercials are different from the census proportions? Carry out test of appropriate hypotheses using a significance level of 0.01. (Let
P₁, P₂, P3, and P4 be the population proportions of the four ethnic groups (African American, Asian, Caucasian, and Hispanic respectively) appearing in commercials on Philadelphia television stations.)
State the appropriate hypotheses.
O Ho: P₁ = 0.145, P₂ = 0.027, P = 0.809, P4 = 0.020
H₂: at least one p₁ # Pio
O Ho: P₁ = 0.177, P₂ = 0.030, P3 = 0.734, P4 = 0.059
H₂: at least one p; # Pio

State the conclusion in the problem context.
O Fail to reject Ho. There is enough evidence to conclude that at least one of the racial proportions in commercials is a match to the census proportions.
O Reject Ho. There is enough evidence to conclude that at least one of the racial proportions in commercials is not a match to the census proportions.
O Reject Ho. There is enough evidence to conclude that none of the racial proportions in commercials is a match to the census proportions.
O Fail to reject Ho. There is enough evidence to conclude that all of the racial proportions in commercials are a match to the census proportions.
