BFW Publishers The Pew Research Center asked a random sample of 2024 adult cell-phone owners from the United States their age and which type of cell phone they own: iPhone, Android, or other (including non-smartphones). The two-way table summarizes the data. Age OP(iPhone and 18-34) = 0.083 and 18-34 35-54 55+ Total Are the events "iPhone" and "18-34" independent? Justify your answer. iPhone Android 214 189 100 169 171 127 467 503 Type of cell phone Other 134 277 643 1054 Total 517 637 870 2024 P(iPhone and not 18 34) = 0.147 Because these two probabilities are not equal, the events "iPhone" and "18-34" are not independent. OP(iPhone) = 0.231 and P(iPhone 18-34) = 0.083 Because these two probabilities are not equal, the events "iPhone" and "18-34" are not independent. P(iPhone) = 0.231 and P(iPhone 18-34)=0.327 Because these two probabilities are not equal, the events "iPhone" and "18-34" are independent. P(iPhone) = 0.231 and P(iPhone 18-34) = 0.327 Because these two probabilities are not equal, the Yents "iPhone" and "18-34" are not independent.
