One Sample sign Test

In a one  sample  test the  null  hypothesis μ=μ0 against an  appropriate alternative on the basis of a random sample of size n we replace each sample value greater  than μ with a  plus sing  and each sample  value less than μ0 with a minus sign and  discard sample value  exactly equal to put 0. We then  test the null hypothesis that these plus and  minus sings are values  of a random  variable having the binomial  distribution with p =1/2.
