Run your correlation analysis. Your cells should include your
deviations, squared deviations (including, SSx and SSy), products
(including SP), computed r coefficient, computed t-value, degrees
of freedom, and critical t-value.

Suppose that the amount of money spent per week on groceries is
normally distributed with an unknown mean and standard deviation. A
random sample of 20 grocery bills is taken and gives a sample mean
of $79 and a sample standard deviation of $13.
Use a calculator to find a 95% confidence interval estimate for
the population mean using the Student's t-distribution.
