Answer 1

Ho: p=0.5 H, :P +0.5 (Two failed test) n = 488 +399 = 887, 2=0.01 Sample Proportion 1 = x = 488 = 10.5502 1 887 test stalistici P p Z = [Px (1-P) In 015502-0.5 . = 2.990 (0.5*(1-015) 2.99 [7= 2.997 Ant P-value = 2 [1- Pr(7 = 2.99)] = [0-0048 fue ) The result is significant at Pax=000 Since, P- value is less than the daood So, we Reject the Ho • There is a sufficient evidence to warrant rejection of the claim that the responses are equivalent to a coin foss.
