Paul owns a mobile wood-fired pizza oven operation. A couple of his clients complained about his dough at a recent catering, so he changed his dough to a newer product. Using the old dough, there were 6 complaints out of 385 pizzas. With the new dough, there were 16 complaints out of 340 pizzas. Let p1 be the proportion of customer complaints with the old dough and p2 be the proportion of customer complaints with the new dough. Paul wants to determine if the proportion of customer complaints using the old dough is less than that using the new dough. Based on a 95% confidence for the difference of the proportions, what is your decision and conclusion? Paul owns a mobile wood-fired pizza oven operation.
