In this case, it is the opposite of the alternative hypothesis.

H0: The average salary for all jobs in Minnesota is greater than or equal to $65,000.

H0: x ≥$65,000 Formulation of the Alternative Hypothesis –the alternative hypothesis is the opposite of the null hypothesis, which states that a value is less than, greater than, or not equal to a certain value. This ...

Importance of Confidence intervals

The confidence interval is a set or range of values that a population parameter is likely to fall within (Graham, 2008). It is calculated using the sample statistics and a given confidence level. For instance, a confidence interval of the mean calculated using the sample statistics, gives the lowest and highest possible value of the population mean. The population mean is expected to be within the confidence interval. A point estimate is a single value that approximates a population parameter (Graham, 2008). For instance, a sample mean is point estimate of the population mean, while a sample proportion is ...

In this case, we illustrate the application of multiple regression in economics. We gather data on the unemployment rate (dependent variable) and three independent variables; GDP per capita, maximum weekly unemployment benefit and population estimate for 2015. The data is collected from 39 different states. Regression analysis results show that there is a positive association between the unemployment rate and GDP per capita and population estimate. The relationship between unemployment rate and maximum weekly benefits is inverse. The evaluation of the reliability of the first-order model shows that it has a small coefficient of determination. The first-order model is ...
