Abiotic factors are those that affect living organisms in freshwater systems, and biotic factors affect species in the surrounding area. Although crustaceans, woodlice do not â¦ live in water. Rather, they thrive in damp areas that provide moisture as woodlice rapidly lose hydration through excretion.
all answers 6 null hypothesis are never accepted we either reject them or fail to reject them the distinction between acceptance and failure to reject is best understood in terms of confidence intervals failing to reject a hypothesis means a confidence interval contains a value of no difference however the data may also be consistent with differences of practical importance hence failing to reject the null hypothesis does not mean that we have shown that there is no difference accept the null hypothesis
If the P-value is less than the significance level, we reject the null hypothesis. Region of acceptance. The region of acceptance is a range of values. If the test statistic falls within the region of acceptance, the null hypothesis is not rejected.wo types of errors can result from a hypothesis test. 1  Type I error. 2  A Type I error occurs when the researcher rejects a null hypothesis when it is true. 3  The probability of committing a Type I error is called the significance level. 4  This probability is also called alpha, and is often denoted by Î±. 5  Type II error.
