What are the nu and athemative hypotheses? Hos p P44 versus H1 p I A4 (Round to two decima plaoes as needed Use technology to find the P value. p value. (Round to three decimal places as needed)

Explanation / Answer

Ho: p = .44
Ha: p <.44

Z = ((105/250)-.44)/(sqrt(.44*.56/250))
= -.64

So, P(Z<-.64)
=1-.7389
=.2611>.1
So, we don't reject Ho and conclude that p =.44 is right
