Jennifer was doing an experiment to find out which type of plant would grow the tallest in one month. for her experiment, jennifer chose four types of plants. she then put each plant in soil, placed the plants on the window, and watered the plants daily. she repeated the trial three times and recorded her results in the tables below
plant type growth (in inches)
1 5 in.
2 17 in.
3 8 in.
4 2 in.
plant type growth (in inches)
1 15 in.
2 8 in.
3 24 in.
4 17 in.
plant type growth (in inches)
1 21 in.
2 6 in.
3 14 in.
4 9 in.
from the results above, jennifer concluded that plant 1 grew the tallest in one month's time. is this a valid conclusion?
a yes. the data from the first two trials are wrong, and plant 1 is really the tallest.
b no. the data were different in each trial, so one valid conclusion could not be made.
c no. plant 2 grew the tallest of all the types of plants that she studied.
d yes. plant 1 was tallest in one of the trials, so the conclusion is valid.
