Given that 
and 
, given that the population mean is 
and the sample size is n = 16, the test statistic is given by
Since the test is a two tailed test, the p-value is 2(0.07493) = 0.14986
Since the p-value is greater the significant level of α = 0.01, thus, we fail to reject the null hypothesis and conclude that there is no sufficient evidence that <span>the percentage of wheat crop lost to hail in that county is different from the national mean of 11%</span>.
