You are running a business that manufactures sneakers. A women's size 9 sneaker is known to have a length of 10 inches. You are concerned that the sneakers being produced are too large. You randomly sample 24 sneakers and calculate a sample mean of 10.31 inches with a standard deviation of 0.87 inches. Using this data, you conduct a significance test with a significance level of α = 0.05 and calculate a t-value of 1.75. Make a strategic decision based on the result of this test. You should continue producing the sneakers using the current methods. You should redesign the shoe to be slightly larger and recalibrate them machines producing them. You should redesign the shoe to be slightly smaller and recalibrate the machines producing them. You should continue producing the sneakers but relabel them to be a different size.
