Please type your subject in the School Subject box. Any other words, including obscure abbreviations, are likely to delay responses from a teacher who knows that subject well.
I assume you are referring to SPSS in your subject line, which is a computer program for analyzing statistical data. If so, conduct a one-sample t-test using the data you have entered in your post. If you are unfamiliar with SPSS, there are online tutorials which may help.
