    Help with math project?

    I need a null hypothesis for a statistics project. Here is the run down: surveyed 63 people (53F 10M) on the preferrence of laptop vs desktop. 37 (58.73%) said laptop 26(41.27%) were desktop. The data also determined that 93.55% of people actually enjoy using their personal computers for home and leisure, with school coming in at 35.48%, and office/work at the same percentage (35.48%). This data chart shows if the individual voted that they are a 5 when it comes to being technologically inclined, which form of personal computer do they actually prefer. Here we see that 65.22% of the sample that voted themselves as a 5 actually prefer laptops over desktops, which is no surprise because of the sheer quantity of people who enjoy laptops as a whole over desktops.

    Null Hypothesis should be status quo. Try "there is not difference in preference" - or something like that.

    A null hypothesis is a declaration that there is no relationship between various factors that you're researching. Often, the null hypothesis is the opposite of what you're trying to prove.

    EG: Conservatives believe that public shaming will reduce the abortion rate.

    Hypothesis (H): Mandatory trans\/aginal ultrasounds reduce the abortion rate

    Null Hypotheses (H0): Mandatory trans\/aginal ultrasounds do not reduce the abortion rate

    In your case, these seems to be some relationship between a person's perceived level of technical prowess and the type of computer they prefer. Come up with a hypothesis. The null hypothesis would then be the opposite. If you can disprove the null hypothesis, then the hypothesis is true.
