    As you suggested I plotted yes/no vs percentage and came up with the graph that I attached here. But I can’t conclude any regression from this plot. Is this the plot you meant?

    this is the explanation from minitab; alpha which is the risk of concluding that the mean of Yes differs from the mean of No when in fact it doesn’t, is .05. if the p-value is less than .05, you can conclude that the mean of Yes differs from No at the .05 level of significance.

    I kind of don’t understand why. we calculate t-value then transfer that into p-value. when the p-value gets bigger the t-value gets smaller. and for a smaller t-value the probability that we say there is no difference while there is difference gets higher. what am i missing here?

    Thanks @rbutler, that helped.

    How can I run regression while one column of the table is just “Yes” and “No”?

    Could you please explain how can I interpret the P=.127?
