John was calculating the peeds (mph) of vehicles traveling down Maple Street on two separate days at 9 am for an hour. Below is the data she collected. Wednesday's speeds: 32,28,24,17,39,44,64,33,27,21,38,40,60,30,25,37,30,25,35,30 Sunday's speeds: 18,27,34,37,49,55,63,61,48,30,27,17,17,15,26,46,25 1. Calculate the mean and median of each day. 2. Calculate the five-number summary of each day. a. Wednesday's Five-Number Summary. b. Sunday's Five-Number Summary. 3. Test each day for outliers. If they have outliers, identify them and adjust the five-number summary to reflect the outlier. (Remember to find IQR and then Upper and Lower Limits) a. Wednesday's Outlier Test b. Sunday's Outlier Test 4. Create a stacked box-and-whisker plot using the five-number summaries from Wednesday and Sunday. 5. What do you notice about the box-and-whisker plots? Describe the spread in each specifically.

Question
Transcribed Image Text:John was calculating the peeds (mph) of vehicles traveling down Maple Street on two separate days at 9
am for an hour. Below is the data she collected.
Wednesday's speeds: 32,28,24,17,39,44,64,33,27,21,38,40,60,30,25,37,30,25,35,30
Sunday's speeds: 18,27,34,37,49,55,63,61,48,30,27,17,17,15,26,46,25
1. Calculate the mean and median of each day.
2. Calculate the five-number summary of each day.
a. Wednesday's Five-Number Summary.
b. Sunday's Five-Number Summary.
3. Test each day for outliers. If they have outliers, identify them and adjust the five-number
summary to reflect the outlier. (Remember to find IQR and then Upper and Lower Limits)
a. Wednesday's Outlier Test
b. Sunday's Outlier Test
4. Create a stacked box-and-whisker plot using the five-number summaries from Wednesday and
Sunday.
5. What do you notice about the box-and-whisker plots? Describe the spread in each specifically.
