A hypothesis testing: H0: p=0.49 HA: p<0.49.


A hypothesis testing: H0: p=0.49 HA: p<0.49. 

We conduct a survey with sample size n=171 and have pˆ=0.39. With α=0.05, do you reject or fail to reject the Null hypothesis? Enter 1 if you "reject the Null hypothesis" and 0 if you "fail to reject the null hypothesis".

Note:
1- Enter either 0 or 1 in the box. The box does not accept text as an answer. Your answer should be either 0 or 1 and no other answers will be accepted.
