How much money does the average professional hockey fan spend on food at a single hockey game? That question was posed to 10 randomly selected hockey fans. The sampled results show that sample mean and standard deviation were $18.00 and $2.8, respectively. Use this information to create a 95% confidence interval for the mean. Express the answer in the form x ± ta/2(s/n). 18 + 2.228(2.8//10) 18 + 2.262(2.8/10) 18 ± 1.833(2.8/^10) 18 ± 2.201(2.8/10)
