Question 903025
Ho: p = 0.017
Ha: p > .017 
-----------------------------------------
sample proportion = p-hat = 19/800 = 0.02375
---
test stat:: z(0.02375) = (.024-.017)/sqrt[0.017*0.983/800] = .007/.00457 = 1.53
-----
p-value = P(z > 1.53) = 1 - P(z<1.53) = 1 - .94 = .06
---------------------
Conclusiion: 
Since the p-value is greater than 5%, accept Ho.
 there is not sufficient evidence to conclude that more than 1.7% results
