Suppose that the following is to be tested: Ho: p = 0.35 and Hi: p ˃0.35. Calculate the observed z-statistic for the following sample data: Forty out of eighty test subjects have the characteristic of interest. Assume p approximates a normal distribution and α = 0.01. Is the null hypothesis rejected or failed to be rejected?
