I want to know can I conclude the data come from normal population?

I want to know can I conclude the data come from normal population? also Shapiro.test show

shapiro.test(data$t)

data: data$t W = 0.97075, p-value = 2.072e-07

how I can interpret this?

Solution

Since p-value is less than 0.05 so we reject the null hypothesis that  the data come from normal population. Also the QQ plot shows that distribution is left tailed. That is it is not symmetric. So on the basis of evidence givem, we cannot conclude that  the data come from normal population.
