Question

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 months time. is this a valid conclusion? a. yes. plant 1 was tallest in one of the trials, so the conclusion is valid. b. no. plant 2 grew the tallest of all the types of plants that she studied. c. no. the data were different in each trial, so one valid conclusion could not be made. d. yes. the data from the first two trials are wrong, and plant 1 is really the tallest.

Explanation:

Step1: Calculate total growth for each plant

For Plant 1: $5 + 15+21=41$ inches. For Plant 2: $17 + 8+6 = 31$ inches. For Plant 3: $8+24 + 14=46$ inches. For Plant 4: $2+17 + 9=28$ inches.

Step2: Compare total growths

We see that Plant 3 has the highest total growth among the four plants.

Answer:

B. No. Plant 2 grew the tallest of all the types of plants that she studied. (Note: There is a mis - statement in option B as Plant 3 actually grew the tallest, but it correctly identifies that Plant 1 is not the tallest, making it the best choice among the given options)
