A random sample of 11 observations was taken from a normal population. The sample mean and standard deviation are xbar= 74.5 and s= 9. Can we infer at the 5% significance level that the population mean is greater than 70?

I already found the test statistic (1.66) but I’m at a loss for how to find the p-value.
