Find the range and interquartile range of the data. round to the nearest tenth. 183, 339, 284, 111, 134, 344, 133 a. range=211; interquartile range= 206 b. range=233; interquartile range= 206 c. range= 233; interquartile range= 156 d. range= 211; interquartile range= 156

We first need to list the following Data Set:

111, 133, 134, 183, 284, 334, 339

Range = highest value - lowest value =

Range = 339 - 111 = 228

Interquartile range = upper quartile - lower quartile =

(or IQR = interquartile range, another term)

Interquartile range = 334 - 133 = 201

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
