Q:

The line plots show the number of hours two groups of kids spent studying last weekend.How does the data compare for the two groups of kids?The 10- to 13-year olds spent an average of 6 hours studying last weekend.The range for the hours spent studying last weekend for the 10- to 13-year olds is the same as the range for the hours spent studying last weekend for the 14- to 17-year olds.The median value for the hours spent studying last weekend for the 10- to 13-year olds is greater than the median value for the hours spent studying last weekend for the 14- to 17-year olds.The 14- to 17-year olds spent more hours studying, on average, last weekend than the 10- to 13-year olds.

Accepted Solution

A:
We can conclude that: the 14- to 17-year olds spent more hours (6.8 hours) studying, on average, last weekend than the 10- to 13-year olds (4.3 hours).What is Range, Median, and Average of a Data Distribution:Range = max - minMedian = middle valueAverage = total sum of values/number of values.Range for hours spent studying for 10 - 13 year olds = 8 - 1 = 7Range for hours spent studying for 14 - 17 year olds = 10 - 4 = 6Median for hours spent studying for 10 - 13 year olds = 4Median for hours spent studying for 14 - 17 year olds = 7Average for hours spent studying for 10 - 13 year olds = (1+1+2+4+4+4+4+6+6+7+8)/11 = 4.3Average for hours spent studying for 14 - 17 year olds = (4+4+4+4+6+7+8+9+9+10+10)/11 = 6.8Therefore, we can conclude that: the 14- to 17-year olds spent more hours (6.8 hours) studying, on average, last weekend than the 10- to 13-year olds (4.3 hours).Learn more about average, range, and median on:
