In a winter of an epidemic flu, 2 ,000 babies were surveyed by a well -known pharmaceutical company to determine if the company's new medicine was effective after two days.
00:10
Among 120 babies who had the flu and were given the medicine, 29 were cured within two days.
00:16
Among 280 babies who had the flu but were not given the medicine were cured within two days.
00:22
So i'm going to go ahead and do medicine and not medicine.
00:26
So we have our first proportion, which is our 29 out of 120, and we have proportion 2, which is our 56 out of 280.
00:47
Is there any significant indication that supports the company's claim of the effectiveness of the medicine? so we can think of a null hypothesis being that there's no difference between our two scenarios and the alternative is that the medication is effective, so it's greater than non -medicated.

29 over 120 is 0 .242 and 56 over 280 is 0 .2...
