Is there enough evidence to reject the claim at a = 0.05? Complete parts (a) through (e) below. Assume the population is normally distributed. (a) Write the claim mathematically and identify Ho and Ha Which of the following correctly states Ho and H? OB. Ho: p= $19,000 H:> 519,000 O A. Ho: 12 $19,000 Hu<$19.000 OD. Ho:p> 519,000 H: 5 $19,000 0 C. Ho: =$19,000 Hu+$19,000 06. Ho: H=519,000 Hu<$19,000 O E. Ho: u* $19,000 Ha: u = $19,000
