This means that:<br /> A) the objective of a mutual fund is independent of risk level;<br /> B) there is strong evidence to support an association between the objective of a mutual fund and risk level;<br /> C) there is a relationship between the objective of a mutual fund and risk level;<br /> D) there is no significant difference between the objective of a mutual fund and risk level.", "B) there is strong evidence to support an association between the objective of a mutual fund and risk level" "Which of the following is a discrete numerical variable?<br /> a) The daily average temperature.<br /> b) The volume of water released from a dam<br /> c) The distance you drove yesterday.<br /> d) The number of employees of an insurance company", "d) The number of employees of an insurance company" "The manager of the customer service division of a major consumer electronics company is interested in determining whether the customers who have purchased a smart TV made by the company over the past 12 months are satisfied with their products.<br /> The population of interest is<br /> a) all the customers who have bought a smart TV made by the company over the past 12 months.<br /> b) all the customers who have bought a smart TV made by the company and brought it in for repair over the past 12 months.<br /> c) all the customers who have used a smart TV over the past 12 months.<br /> d) all the customers who have ever bought a smart TV made by the company.", "a) all the customers who have bought a smart TV made by the company over the past 12 months." "True or False: The answer to the question “What is your favourite colour?” is an example of an ordinal scaled variable.", "ANSWER: FALSE" "Which one of the following does not measure some form of variation?<br /> (a) The mean.<br /> (b) The standard deviation.<br /> (c) The inter-quartile range.<br /> (d) The standard error.<br /> (e) The range.", "(a) The mean." "In a study of ear infections, a scientist approached swimmers at a Sydney beach and recorded their age, gender, and whether or not they reported an ear infection in the last two weeks. Which recorded variable is a quantitative variable?<br /> (a) Gender.<br /> (b) Age.<br /> (c) Whether or not an ear infection is reported.<br /> (d) The number of reported ear infections.<br /> (e) None of the variables are quantitative.", "(b) Age."

What graph would be used to show the relationship between the two variables?<br /> (a) A bar chart.<br /> (b) A scatterplot.<br /> (c) A histogram.<br /> (d) A boxplot.<br /> (e) A stem-and-leaf plot", "(b) A scatterplot." "An R-square of .885 means that the data fits the model:<br /> a) Very well<br /> b) Moderately well<br /> c) Poorly<br /> d) Not at all", "a) Very well (R-square of 88.5 %)" "When we say the true regression slope is different from zero…this means:<br /> a) Observations do not include the zero value<br /> b) The dependent variable is not related to the independent variable<br /> c) A real average linear relationship exists between the two variables<br /> d) The p value is not zero", "c) A real average linear relationship exists between the two variables" "When we find a p-value for distance to be less than α (alpha = 0.05), this means that the true regression slope is:<br /> a) Not related<br /> b) Independent<br /> c) Not zero<br /> d) Not to be interpreted, as the p value cannot be zero", "c) Not zero" "An R-square of 0.885 means that:<br /> a) 88.5% of the variation in the dependent variable can be explained by the variation in the independent variable<br /> b) The dependent variable is not related to the independent variable<br /> c) A real average linear relationship exists<br /> d) That the p value is not zero", "a) 88.5% of the variation in the dependent variable can be explained by the variation in the independent variable"
