    John Morrell & Company is the oldest continuously operating cheese manufacturer in the United States, dating back to 1827 in England. It offers processed cheese under 13 regional brands and conducts market research to understand consumer preferences. A recent study compared Morrell's cheese pot roast to two competitors' products in terms of taste, appearance, aroma, and preference. The hypothesis test aimed to determine if Morrell's product was preferred by over 50% of consumers. A sample of 224 consumers selected Morrell's product as their preference, allowing the null hypothesis that preference was below 50% to be rejected in favor of the alternative hypothesis.

    JOHN MORRELL& COMPANY

    CINCINNATI, OHIO

    John Morrell & Company, which began in England in 1827, is considered the oldest continuously
    operating Cheese manufacturer in the United States. It is a wholly owned and independently
    managed subsidiary of Smithfield Foods, Smithfield, Virginia. John Morrell & Company offers an
    extensive product line of processed Cheese to consumers under 13 regional brands including John
    Morrell, E-Z-Cut, Tobin’s First Prize, Dinner Bell, Hunter, Kretschmar, Rath, Rodeo, Shenson, Farmers
    Hickory Brand, Iowa Quality, and Peyton’s. Each regional brand enjoys high brand recognition and
    loyalty among consumers. Market research at Morrell provides management with up-to-date
    information on the company’s various products and how the products compare with competing
    brands of similar products.

    A recent study compared a Cheese Pot Roast made by Morrell to similar Cheese products from two
    major competitors. In the three-product comparison test, a sample of consumers was used to
    indicate how the products rated in terms of taste, appearance, aroma, and overall preference. One
    research question concerned whether the Cheese Pot Roast made by Morrell was the preferred
    choice of more than 50% of the consumer population. Letting p indicate the population proportion
    preferring Morrell’s product, the hypothesis test for the research question is as follows:

    The null hypothesis H0 indicates the preference for Morrell’s product is less than or equal to 50%. If
    the sample data support rejecting H0 in favor of the alternative hypothesis Ha, Morrell will draw the
    research conclusion that in a three-product comparison, their Cheese Pot Roast is preferred by more
    than 50% of the consumer population.

    In an independent taste test study using a sample of 224 consumers in Cincinnati, Milwaukee, and
    Los Angeles, 150 consumers selected the Cheese Pot Roast made by Morrell as the preferred
    product. Using statistical hypothesis testing procedures, the null hypothesis H0 was rejected. The
    study provided statistical evidence supporting Ha and the conclusion that the Morrell product is
    preferred by more than 50% of the consumer population.

    The point estimate of the population proportion was p = 150/224 = 0.67. Thus, the sample data
    provided support for a food magazine advertisement showing that in a three-product taste
    comparison, Cheese Pot Roast made by Morrell was “preferred 2 to 1 over the competition.”

    In hypothesis testing we begin by making a tentative assumption about a population parameter. This
    tentative assumption is called the null hypothesis and is denoted by H0. We then define another
    hypothesis, called the alternative hypothesis, which is the opposite of what is stated in the null
    hypothesis. The alternative hypothesis is denoted by Ha.
