The Z test problem is written

(6.8-6.2)/(.5/sqrt36)

A)I have the Ho: u<=6.8 H1: u.6.8

B)State the decision rule?

I cant figure this out the significance level is .05 and the standard deviation is .5


C)compute the test statistic

(6.8-6.2)/(.5/sqrt36)=.6/.083= 7.22

Z=7.22

D)what is your decision regarding the Ho?

Ho is accepted


Can someone please help on part B
