Researchers examined the influence of a television program on children's aggressiveness. The number of aggressive responses was measured during an observation period after viewing the television program. Imagine that the known national average for number of aggressive responses typically performed by children who do not watch television is 6.847. Use the data below to conduct an analysis to determine if the number of aggressive responses on average is different from the national average.

Number of aggressive responses:
9, 4, 11, 12, 14, 7, 12

b) Is the assumption(s) met? Please explain your answer and proceed with the analysis even if the assumption(s) is not met.

c) What do you conclude from your analysis?

d) Based on your decision in “c” above, identify and explain the type of error you could be making with respect to the conclusion of the study.
