Write the hypotheses to test the claim the “with the XSORT method, the proportion of girls is greater than the 50% that occurs without any treatment”. The correct way of Writing the null and alternative hypotheses:

Question 8 options: Ho : P = 0.5 H1 : P > 0.5 Ho : P = 0.5 H1 : P < 0.5 Ho : P = 0.58 H1 : P < 0.58 Ho : P = 0.58 H1 : P > 0.58

Explanation / Answer

Solution :

Given that ,

The proportion of girls is greater than the 50% that occurs without any treatment .
