Calculate the p-value for the following conditions and determine whether or not to reject the null hypothesis.

a)one-tail test, zx=1.50, and =0.01	b)one-tail test, zx=negative -2.85, and=0.10
c)two tailtest,zx=2.10, and =0.01	d)two-tail test, zx-=-1.39, and =0.05

a) The p-value is ____ (Round to four decimal places asneeded.)

Since=0.01,(Reject or do not reject)the null hypothesis.

b) The p-value is ______(Round to four decimal places asneeded.) Since=0.10,(Reject or do not reject)the null hypothesis

c)The p-value is ______(Round to four decimal places asneeded.)

Since=0.01,(Reject or do not reject)the null hypothesis d)The p-value is ______(Round to four decimal places asneeded.)

Since=0.05,(Reject or do not reject)the null hypothesis
