Consider the following. (Give your answers correct to two decimal places.) (a) Calculate the test statistic z used in testing H o : p = 0.70, H a : p > 0.70; with the sample n = 320 and x = 257. (b)...

(a) Calculate the test statisticz used in testingH
_o:p = 0.70,H
_a:p > 0.70; with the samplen = 320 andx = 257.




(b) Calculate the test statisticz used in testingH
_o:p = 0.50,H
_a:p < 0.50;="" with="" the="">n = 430 andx = 204.




(c) Calculate the test statisticz used in testingH
_o:p = 0.35,H
_a:p ≠ 0.35; with the samplen = 292 andx = 89.




(d) Calculate the test statisticz used in testingH
_o:p = 0.90,H
_a:p > 0.90; with the samplen = 543 andx = 514.
