40.A relationship is linear if the scatter plot of the independent and dependent variables has a straight-line pattern. 41.The sum of squares error (SSE) represents the random variation in the data not attributed to either the main factor or the blocking factor. 42.Nintendo Sony would like to test the hypothesis that a difference exists in the average age of users of a Wii, a PlayStation, or an Xbox console game. The following data represent the age of a random sample of Wii, PlayStation, and Xbox users.The mean square total for these observations is ________. 43.The experiment-wide error rate is the probability of committing a Type II error for atleast one pair of population means being compared. 44.Randomized block ANOVA should not be used to test the significance of the blocking factor. Under these circumstances, a two-way ANOVA procedure is more appropriate. 45.Including a blocking factor in the ANOVA procedure can sometimes hinder the ability to correctly detect a difference in population means. 46.The critical value for the Tukey-Kramer critical range is found using theF-distribution. 47.The sum of squares within (SSW) measures the variation between each data value of the grand mean for all of the data. 48.The total sum of squares (SST) measures the amount of variation between each data value and the grand mean. 49.Consider the partially completed one-way ANOVA summary table.
The total number of observations for this ANOVA procedure is ____. 50.A(n) ________ in ANOVA describes a category within the factor of interest. 51.Consider the relationship between the following variables:Household IncomeSquare footage of the primary residenceHousehold income would be considered the independent varialble. 52.Two variables have a correlation coefficient equal to +0.55 from a sample size of 8.Which one of the following statements describes the results of the hypothesis test that the population correlation coefficient is greater than zero using α= 0.05? 53.A scatter plot is a useful tool to examine the data before conducting correlation analysis. 54.The ________ is used to test the significance of the population correlation coefficient.
