b An item A is manufactured using certain process Item B serves the same function as A but

manufactured using a new process The manufacturer wishes to detennine whether B is preferred to A by the consumer so she selects a random sample consisting of 10 consumers gives each of them oneA and one B and asks them to use the items for some period of time At the end of the allotted period of time the consumers report their preferences to the manufacturer Eight consumers preferred B to A 1 preferred A to B and 1 reported no preference Use an appropriate test to fmd out the manufacturers decision at 5 level of significance Also calculate the P-value
