Given the mean and SD of the eight forms of employment in PEAR INC., calculate the z-scores for the individuals who took the exams in the different countries. ROUND Z-SCORES TO THREE DECIMAL PLACES; WRITE Z-SCORES WITH A SIGN (ex. -1.204 for negative z-score and +1.204 for positive) Description Quiz 11: Z-Scores   ROUND Z-SCORES TO THREE DECIMAL PLACES (to the nearest thousandth). EACH Z-SCORE SHOULD HAVE A + OR - SIGN IN FRONT TO INDICATE POSITIVE OR NEGATIVE VALUE. Use the data below: Eight forms of an employment exam (one in each country of expansion) are given by PEAR INC.  The overall (population) mean and standard deviations of these eight forms are found in the table below.

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. The data for this study can be found below, answer questions based on data. What is the null and alternative hypotheses in words and symbols? Is the assumption(s) met? Please explain your answer and proceed with the analysis even if the assumption(s) is not met.    What do you conclude from your analysis?   Based on your response in “c” above, identify and explain the type of error you could be making.   responses 9 4 11 12 14 7 12 10 11 8 14 12 8 12 7 10 10 9 5…
