<h3>What is Gross Domestic Product (GDP)?</h3>

The term "Gross Domestic Product," or GDP, refers to the total monetary worth of all finished goods and services produced (and marketed) within a nation within a specific time period (typically 1 year).

GDP Growth Rate:

  • The GDP growth rate compares the most recent quarter or year to the preceding one and represents the percentage change in real GDP (GDP adjusted for inflation) from one period to the next.
  • A positive or negative number may be used (negative growth rate, indicating economic contraction).

GDP per capita:

  • By dividing nominal GDP by a nation's entire population, one can get GDP per capita.
  • It conveys the nation's average economic output (or income) per person.
  • The population figure corresponds to the year's median (or mid-year) population.

The price deflator, a statistical tool, is used to convert nominal GDP to constant prices.

elixir [45]

Answer:

Because the test statistic is less than the critical value, we can reject the null hypothesis  and conclude that the population correlation coefficient is less than zero.

Explanation:

Because the question is based on the hypothesis test of the significance of the correlation coefficient to decide whether the linear relationship in the sample data is strong enough to use to model the relationship in the population. If the tests concludes that the correlation coefficient is not significantly different from zero, it means that the correlation coefficient is not significant.

This is a psychological phenomenon which states that the desire for maintaining a cooperative and harmonious nature within a group leads individuals in that group to behave irrationally leading to bad decision-making choices.
