Prior to the virus outbreak in Maine, a one-pound box of pasta cost $1.09 cents. You sample 24 grocery stores and find that the average cost is X-bar = $1.39 cents with a standard deviation s = 12 cents (or $0.12). You want to see if this is significantly different from the cost before the outbreak, so you test the following hypotheses: Ho: µ = 1.09 and Ha: µ # 1.09. What is the standard error of the mean? Round your answer to three decimal places.
