Consider the following argument. If an infinite series converges, then the terms go to 0. The terms of the infinite series [infinity] n=1 1 n go to 0. ∴ The infinite series [infinity] n=1 1 n converges. Which of the following choices correctly describes whether the argument is valid or invalid and includes a correct justification? Valid, universal modus tollens. Valid, universal modus ponens. Invalid, converse error. Invalid, inverse error.

1. why is a frequency distribution useful? it allows researchers to see the "shape" of the data. it tells researchers how often the mean occurs in a set of data. it can visually identify the mean. it ignores outliers. 2. the is defined by its mean and standard deviation alone. normal distribution frequency distribution median distribution marginal distribution 3. approximately % of the data in a given sample falls within three standard deviations of the mean if it is normally distributed. 95 68 34 99 4. a data set is said to be if the mean of the data is greater than the median of the data. normally distributed frequency distributed right-skewed left-skewed
