The dot plots below show the weights of the players of two teams: Two dot plots are shown one below the other. The top and the bottom plots have the title Team A and Team B respectively. Below the line for each dot plot is written Weight followed by pounds in parentheses. The markings on each line are from 120 till 140 at intervals of 1. For the top plot there are two dots each for 120, 121 and 126 and 1 dot each for 123, and 128. For the bottom plot there are 2 dots each for 130 and 139 and 1 dot each for 126, 127, 132, and 135.

Based on visual inspection of the dot plots, which team appears to have the larger mean weight?

Team A

Team B

Both groups are similar.

Not enough information is available to draw a conclusion.

the scientific method.

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
