Aresearcher wanted to study the effect of low light environments on the growth of alfalfa plants, so she grew six plants and measured their heights after two weeks. she calculated a sample mean of 5.35 cm and a sample standard deviation of 0.90 cm. if the heights of the first five plants in her sample were 6.0 cm, 5.9 cm, 4.0 cm, 5.5 cm, and 6.2 cm, what is the height of the other plant?

Height of the other plant is cm

Explanation:

- Given -

Mean of the sample set of plants cm

Mean of a given set of data is equal to the sum of integral values of each data divided by the number of such data points

Where M signifies the Mean values

X signifies the sum of all unit data with in a sample

and n signifies total number of data units with in a sample

On substituting the given values in above equation, we get -

Hence, height of the other plant is cm

ur answer is e & d

explanation:

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
