Please help on a timed quiz The heights, in feet, of the trees for sale at two nurseries are shown below,Yard Works: 7, 9, 7, 12,5The Grow Station: 9, 11, 6, 12,7Which statements are true regarding the measures of center and variability of these data sets? Select three choices.A) The mean of the tree heights at Yard Works is less than the mean of the tree heights at The Grow Station.B) The median of the tree heights at Yard Works is greater than the median of the tree heights at The Grow Station.C) The range of the tree heights at Yard Works is greater than the range of the tree heights at The Grow Station.D) The mean absolute deviation of the tree heights at Yard Works is greater than the mean absolute deviation of the tree heights at The Grow Station. E) The mean absolute deviation of the tree heights at Yard Works is equal to the mean absolute deviation of the tree heights at The Grow Station

Question
Answer:
Answer: The range of the tree heights at yard work is greater than the range of the tree heights at the grow stationStep-by-step explanation:yard works: 7,9,7,12,15The grow station:9,11,6,12,7mean of yard works = 7+9+7+12+15/5=50/5=10mean of grow station=9+11+6+12+7 /5=45/5 =9The mean of tree heights at yard work is greater than that of grow station.median(tree at yard work):7,7,9,12,15median=9median(tree at grow station)=6,7,9,11,12median=9The median of the tree height at yard work is equal to the median of that of tree station. Range(yard work) = 15 - 7 =8Range (tree station) =12-6=6The range of the tree heights at yard work is greater to the tree heights at that of tree station
