<PRE><B>Question 1079684</B>
A random sample of n = 1200 observations from a binomial population produced x = 689.
p-hat = 689/1200 = 0.5742
z(0.5742) = (0.5742-mean)/std
Comment:: Insufficient information to calculate the mean and std.

(b) Calculate the test statistic and its p-value. (Round your test statistic to two decimal places and your p-value to four decimal places.) 
z = 
p-value = </PRE>
