Suppose that you asked 35 randomly selected customers about the product. Their responses were as follows: 192 88 70 192 146 27 135 58 69 154 58 15 192 58 27 231 231 58 192 192 85 146 108 38 100 40 77 269 20 Assume that E(x-x_bar)2 for this sample = 150709. Construct a 95% confidence interval for the monthly average spending on yogurt
