In an experiment to learn if substance M can help restore memory, the brains of20rats were treated to damage their memories. The rats were trained to run a maze. After a day,10rats were given M, andseven of them succeeded in the maze; onlythreeof the10control rats were successful. Theztest for "no difference" against "a higher proportion of the M group succeeds" has what values for thez-statistic andP-value? (Round yourz-value to two decimal places and your P-value to three decimal places.)
