1 1 point The mean value in a dataset is 50. A data value of 42 is 1.33 SDs below the mean. What is the value of one standard deviation? Enter your response as a positive or negative whole number. Type your answer.2 points 5? Decide whether each statement about standard deviation applies to a population or a sample. you divide by the group size when A calculating SD sample group size is represented with n population group size is represented with N v standard deviation is represented by a V lowercase s standard deviation is represented by a v lowercase sigma you divide by one less than the group v size when calculating SD 3 1 point The mean value in a dataset is 100, and the value of one standard deviation is 20.
