7. [-/7 Points] DETAILS A random sample of 174 university students was selected, and both the email service provider and cell phone provider were determined for each one, resulting in the accompanying data. State and test the appropriate hypotheses. (Test whether cell phone provider has an effect on email provider.) Cell Phone Provider ATT Verizon Other gmail 29 16 25 Email Provider Yahoo 35 Other 23 17 USE SALT State the appropriate hypotheses. Ho: P1₁ P12 P₁3 for i=1, 2, 3 H₂: all p's are equal O Ho: P₁₁ P₁2 P₁3 for i = 1, 2, 3 H.: at least one pijPj for i=1, 2, 3 and j = 1, 2, 3 = O H₂¹ P₁₁ = P₁2 = P₁3 for i = 1, 2, 3 Ho: H.: at least one p₁, P, for i = 1, 2, 3 and j = 1, 2, 3 O Hot P₁₁ = P₁2 P₁3 for i = 1, 2, 3 = H: no pj's are equal р Compute the expected value for the students who use gmail and Verizon.
