How can i show that the results are significant or not through a test?

[#1]

I have done a survey where the respondents could choose between two different ads. My hypothesis is that most of them would choose the second one (the one on the right). Is there any tests I can use to show if there is a significant difference or not?

Please help

Hi

IMO, this could be test by P test. 

You can find the option in red triangle "Test Probability". 

Then, set your expect/Hypo probability.

Chi-S test result will be shown after click Done.

Hope it can help to sovle your problem.

Have a nice day
