A study is being conducted to compare vitamin C and zinc to determine which is better at fighting colds. Customers believe vitamin C is better at fighting colds. What are the appropriate hypotheses for this testing scenario? Let μc equal the mean of the effectiveness of vitamin C and μz equal the mean of the effectiveness of zinc. O Ho: Hc - Hz= 0 Ha Hc - Hz > 0 O Ho: Hc - Hz= 0 Ha Mc-Hz <0 O Ho: Hc - Hz= 0 Ha Mc - Hz #0 o Ho: xe - xz = 0 Hai Xc → Xz > 0 o Ho: Xe – xz = 0 Hai Xi — Xz #0
