Let æ be a random variable representing the percentage of protein content for early bloom alfalfa hay. The average percentage protein content of such early bloom alfalfa should be u = farmer's co-op is thinking of buying a large amount of baled hay but suspects that the hay is from a later summer cutting with lower protein content. A small amount of hay was removed from each bale of a random sample of 50 bales. The average protein content from the samples was determined by a local agricultural college to be -15.8% with a sample standard deviation of 17.2%. A s = 5.3%- At a = .05, does this hay have lower average protein content than the early bloom alfalfa?

Let a be a random variable representing the percentage of protein content for early bloom alfalfa
hay. The average percentage protein content of such early bloom alfalfa should be u = 17.2%. A
farmer's co-op is thinking of buying a large amount of baled hay but suspects that the hay is from
a later summer cutting with lower protein content. A small amount of hay was removed from
each bale of a random sample of 50 bales. The average protein content from the samples was
determined by a local agricultural college to be -15.8% with a sample standard deviation of
S = 5.3%-
At a = .05, does this hay have lower average protein content than the early bloom alfalfa?
