Benefits of Energy Efficiency

Environmental: Increased efficiency can **lower greenhouse gas (GHG) emissions and other pollutants, as well as decrease water use**. Economic: Improving energy efficiency can lower individual utility bills, create jobs, and help stabilize electricity prices and volatility.

What is Considered to Be a “Weak” Correlation?

Absolute value of r | Strength of relationship |
---|---|

r < 0.25 | No relationship |

0.25 < r < 0.5 | Weak relationship |

0.5 < r < 0.75 | Moderate relationship |

r > 0.75 | Strong relationship |

**Represent the dependent variable in rows and the independent variable in column**. Represent the dependent variable in rows and the independent variable in column.

The correlation coefficient between the two variables is **the measure of the slope between the variables in the regression graph**. It is given that the correlation coefficient between X and Y is 0.4 and the correlation coefficient is independent of change of origin and scale but it depends on variables.

c. | Parity & Cyclic redundancy check |

d. | None of the mentioned |

Answer:Cyclic redundancy check |

The strongest linear relationship is indicated by a correlation coefficient of **-1 or 1**. The weakest linear relationship is indicated by a correlation coefficient equal to 0. A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.

Explanation: **crc** is more powerful and it can detect various kind of errors like 2 bit errors.

Efficient market theory states that the price of all stocks trading in the stock market is already priced in, so you don't need to actively research about the stock because every good news or bad news that could possibly be there is already reflecting in the stock.

The coefficient of variation (CV) is a statistical measure of the relative dispersion of data points in a data series around the mean. In finance, the coefficient of variation **allows investors to determine how much volatility, or risk, is assumed in comparison to the amount of return expected from investments**.

4. Which reduces the size of the data? Explanation: **Source coding** reduces the size of the data and channel coding increases the size of the data.

In summary, correlation coefficients are used **to assess the strength and direction of the linear relationships between pairs of variables**.

If r = 1 or r = –1 **the correlation is perfect**. The relation between them is exact.

**If strength and direction of a linear relationship should be presented, then r is the correct statistic**. If the proportion of explained variance should be presented, then r² is the correct statistic.

Answer. MCQ: An efficient market hypothesis **states in which all public or private information is reflected in current market prices is classified as**. **market efficiency**.

Energy efficiency is **the use of less energy to perform the same task or produce the same result**. Energy-efficient homes and buildings use less energy to heat, cool, and run appliances and electronics, and energy-efficient manufacturing facilities use less energy to produce goods.

A correlation of 9 signifies that the correlation explains (9)2=0.81 or **81 percent** of the variation.

Answer C. MCQ: **The ratio of required form of energy obtained from a system as output to the total energy given to it as input** is called its. efficiency.

The coefficient of variation (CV) is **the ratio of the standard deviation to the mean**. The higher the coefficient of variation, the greater the level of dispersion around the mean. It is generally expressed as a percentage.
