Question

As discussed in Part I, researchers had preliminary data suggesting that the pathogen causing WNS is an invasive fungal species (P. destructans) brought to North America from Europe. They had also observed that P. destructans occurs on European bats but rarely causes their death. Preliminary research also suggested that one reason that bats have been dying from WNS is that the disorder arouses them from hibernation, causing the bats to waste fat reserves flying during the winter when food is not readily available. These observations led researchers to speculate that European P. destructans will affect North American bat hibernation at least as severely as does North American P. destructans (Warnecke et al. 2012).

Questions 1. Explicitly state the researchers’ null (H0 ) and alternative hypotheses (HA) for this study.

Explanation / Answer

A null hypothesis is the one which suggests that the variables of the hypothesis are not linked.

The Null and alternative hypothesis for this study will be based on the observation, as they tell us the am with which a person carries out a research. So the hypothesis in this situation must be:

Ho: European P. destructans will not affect North american bat hibernation as severely as does North American P. destuctans

HA: European P. destructans will affect North american bat hibernation as severely as does North American P. destuctans
