From the question we are told that
The population mean for EBR is
The sample mean for Ascension parish is
The p-value is
The level of significance is
The null hypothesis is
The alternative hypothesis is
Here is the population mean for Ascension parish
From the data given values we see that
So we fail to reject the null hypothesis
