**Transcription of Text:**How much money does the average professional football fan spend on food at a single football game? That question was posed to 60 randomly selected football fans. The sampled results show that the sample mean was $70.00 and prior sampling indicated that the population standard deviation was $17.50. Use this information to create a 95 percent confidence interval for the population mean.A) $ 70 \pm 1.833 \left(\frac{17.50}{\sqrt{60}}\right) $B) $ 70 \pm 1.960 \left(\frac{17.50}{\sqrt{60}}\right) $C) $ 70 \pm 1.671 \left(\frac{17.50}{\sqrt{60}}\right) $D) $ 70 \pm 1.645 \left(\frac{17.50}{\sqrt{60}}\right) $**Explanation:**This problem provides data to calculate a 95% confidence interval for the average amount of money a typical professional football fan spends on food at a game. The given options involve different critical values and use the sample mean ($70.00), standard deviation ($17.50), and sample size (60) in calculating the confidence interval. Each option represents a potential confidence interval using a different z-value multiplier.
