“Are we using the same password for all your social networking sites?” A recent survey in the USA found that 32 % of social network users use the same password for all their social networking sites. I assert that the ratio of Greece is less than the ratio of USA. Hence we picked 400 social network users in Greece and they were asked this question and 145 of them said yes. Do you reject the hypothesis? Solve it using p-value approach.
