Question 2 0/1pts Quantiles for the set of heights of students in a class are cut points that Divide the range of a probability distribution into continuous intervals with unequal probabilities Divide the set of heights into continuous intervals with unequal probabilities Divide the set of heights into continuous intervals with equal probabilies None of the above Question 4 0 l 1 Pts The distribution of grades of students in a class is bimodal if Most students took the class twice. Most students had different grades reported at two different times for this class Most students took the class in hybrid modality (e.g., online and in-person} Two grades appeared with higher frequencies than their surrounding grades Two grades with the highest frequencies appeared with equal frequency - Question 6 0 l 1 Pts If the mean is higher than the median, then There are equal number of items larger than and smaller than the mean There are more items larger than the mean, than those smaller than the mean There are fewer items larger than the mean, than those smaller than the mean There are equal number of items larger than and smaller than the median Q) There are more items larger than the median, than those smaller than the median There are fewer items larger than the median, than those smaller than the median Question 1 1 pts The law of large numbers says that O The average of the sample can never become equal to the average of the population 0 The average of the sample is always equal to the average of the population 0 The average of the sample is always less than the average of the population 0 The average of the sample gets closer to the average of the population as the sample gets larger 0 None of the above Question 2 1 pts A sample is the same as the population if Q The sample includes everyone in the population 0 The sample includes exactly half the population 0 The sample includes no one from the population 0 None of the above Question 3 1 pts A randomized controlled trial with case and control cohorts Should never be used in studying the efficacy of a drug or vaccine O An important method to understand the cause-effect relationship O Is achieved by asking an individual which cohort they want to be in O None of the above Question 4 1 pts An exit poll at a polling station is an example of a randomized controlled trial O True O FalseQuestion 5 1 pts The bell curve is O A graph depicting the uniform distribution 0 A graph depicting the normal distribution 0 A graph depicting the Poisson distribution 0 None of the above Question 6 1 pts If the variance of a set of heights of a class of students is high, then 0 The standard deviation is low 0 The average height is high 0 The standard deviation is high 0 None of the above
