TABLE 11-10
an Agronomist Wants to Compare the Crop Yield

question 143

Short Answer

TABLE 11-10
An agronomist wants to compare the crop yield of 3 varieties of chickpea seeds. She plants all 3 varieties of the seeds on each of 5 different patches of fields. She then measures the crop yield in bushels per acre. Treating this as a randomized block design, the results are presented in the table that follows

$$\begin{array} { c r r r } \text { Trial } & \text { Smith } & \text { Walsh } & \text { Trevor } \\\hline 1 & 11.1 & 19.0 & 14.6 \\2 & 13.5 & 18.0 & 15.7 \\3 & 15.3 & 19.8 & 16.8 \\4 & 14.6 & 19.6 & 16.7 \\5 & 9.8 & 16.6 & 15.2\end{array}$$
-Referring to Table 11-10, what is the critical value for testing the block effects at a 0.01 level of significance?

Understand the importance of experimental methods in studying memory, including the use of control conditions.

Understand the social functions of media, including entertainment, social control, and socialization.

Recognize the theories explaining mass media's role in society, such as conflict theory and functionalism.

Identify how mass media can act as agents of social control and social cohesion.
