A dot plot shows The general shape of a distribution The mean, median, and mode The relationship between two variables The interquartile range. A row of a stem-and-leaf chart appears as follows: 3 0 1 3 5 7 9. Assume that the date is rounded to the nearest unit. The frequency of the class is seven The minimum value in the class is 0. The maximum value in the class is 39. The class interval is 5. The test scores for a class of 147 students are computed. What is the location of the test score associated with the third quartile? 111 37 74 75% A statistic is a measurable characteristic of the population. T/F. A parameter is a measurable characteristic of a sample. T/F Three persons earn $8 an hour, six earn $9 an hour, and one earns $12 an hour. The weighted mean hourly wage is $9. T/F Which one of the following is referred to as the population mean? mu s sigma chi What is the lowest level of measurement that a median can be computed? Nominal Ordinal Interval Ratio
