1. A manufacturer of dog food is concerned about the low levels of sales recorded of one of its tinned products and wants to consider removing this product from its line. Before doing so, a limited scale market surveyed of 1000 customers that buy this particular brand of dog food is conducted. Of the people surveyed, 230 said that they would like the manufacturer to keep the product under investigation as one of the products in the manufacturer's line. Use this information to construct the 95% confidence interval for the proportion of all customers of this manufacturing brand that would like the manufacturer to keep the product under investigation as one of the products in the manufacturer's line.
