The cost for a new roof for a bungalow can vary regarding the material it`s made off and also on the roof area. My pinion is that is cheaper to lower the ceiling and raise the roof. The price of a small bungalow is about 2000 dollars. Tom Darkman.
A statistical question is a question that can be answered by collecting data and where there will be variability in the data. This is different from a question that anticipates a deterministic answer.
You can use test statistics to determine whether to reject the null hypothesis. The test statistic compares your data with what is expected under the null hypothesis. The test statistic is used to calculate the p-value. A test statistic measures the degree of agreement between a sample of data and the null hypothesis. Its observed value changes randomly from one random sample to a different sample. A test statistic contains information about the data that is relevant for deciding whether to reject the null hypothesis.
