Question

Eights pots, growing three barley plants each, were exposed to high tension discharge while nine similar pots were enclosed in an earthed wire cage. The number of tillers (shoots) in each pot was as follows:

Caged: 17, 27, 18, 25, 27, 29, 27, 23, 17.
Electrified: 16, 16, 20, 16, 21, 17, 15, 20.
Discuss whether electrification exercises any real effect on tillers.

Answer 1

To determine the effect of electrification on tillers, we can compare the mean number of tillers in pots that were exposed to high tension discharge (electrified pots) versus pots that were enclosed in an earthed wire cage (caged pots).

Step-by-step explanation:

Based on the given information, the number of tillers (shoots) in the pots that were enclosed in an earthed wire cage (caged pots) is 17, 27, 18, 25, 27, 29, 27, 23, and 17. The number of tillers in the pots that were exposed to high tension discharge (electrified pots) is 16, 16, 20, 16, 21, 17, 15, and 20. To discuss whether electrification has any real effect on tillers, we can compare the mean number of tillers in each group and perform a statistical analysis, such as a t-test, to determine if there is a significant difference between the groups.
