An article reported the following frequencies with which ethnic characters appeared in recorded commercials that aired on Philadelphia television stations. Ethnicity: African American Frequency: 69 USE SALT Asian Caucasian 11 O Ho: P₁ P₂ P₂ - P4 -0.250 H.: at least one p, # 0.25 330 State the appropriate hypotheses. Ho: P₁0.177, P₂0.020, P₂0.734, P4 - 0.069 H.: at least one p₁ * Pio In a recent census, the proportions for these four ethnic groups are 0.177, 0.020, 0.734, and 0.069, respectively. Does the data suggest that the proportions in commercials are different from the census proportions? Carry out a 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.) Ho: P₁0.165, P₂0.026, P3 -0.791, P4 -0.017 H₂: at least one p₁ = Pio Hispanic Ho: P₁0.069, P₂0.011, P₂0.330, P4 -0.007 H₂: at least one p₁ = Pio 7 Calculate the test statistic. (Round your answer to two decimal places.) x² =
