Many questions in research can be expressed as two competing statements about the population parameter. These two statements are

called the null and the alternative hypotheses. Usually, the researcher hopes the sample evidence will be in favor of the alternative hypothesis, the new theory. It is important to be able to state the theories that are being put to a test. For the scenario below, write out the hypotheses to be put to the test and define the parameter of interest in context of the problem.

ddd [48]

If data for a time series analysis are collected on an annual basis only, then the option(b) seasonal pattern can be ignored

Time series analysis is a specific way of analyzing a sequence of data points collected over an interval of time

The seasonal pattern is refers to the seasonal characteristics of the time series data. It is the predictable pattern that repeats at a certain frequency within one year, such as weekly, monthly, quarterly, etc.

A horizontal pattern exists when the data fluctuate randomly around a constant mean over time.

A trend pattern exists when there is a long-term increase or decrease in the series.

The cyclical component of a time series refers to fluctuations around the trend, excluding the irregular component, revealing a succession of phases of expansion and contraction

Here, the data for a time series analysis are collected on an annual basis, so the seasonal pattern can be ignored
