Calculate the z-test statistics. Below is the formula for calculating the z-test statistics. where, X¯: mean of the sample. Mu: mean of the population. Web10 aug. 2024 · Notice that the hypothesis test is for a single population proportion. This means that the null and alternate hypotheses use the parameter p. The distribution for the test is normal. The estimated proportion p′ is the proportion of fleas killed to the total fleas found on Fido. This is sample information.

Given a p-value for the test statistic, selected in advance and conventionally 0.05, we reject the null hypothesis if p < 0.05 and therefore accept the alternative hypothesis. This is clearly an application of the law of the excluded middle. Web28 jul. 2024 · The assumption of hypothesis testing is called the null hypothesis. A null hypothesis is a type of assumption used in statistics indicating that there is no significant difference between the samples from the underlying population.
