Which aircraft has the greatest range?
The Boeing 777-200LR is the world’s longest range airliner with a range of 17,395km (9,395nmi). The aircraft was rolled out by Boeing in February 2005 and can carry 301 passengers in a typical three-class configuration.
How does the position of Centre of gravity of an airplane affect its performance?
The effect of the position of the CG on the load imposed on an aircraft’s wing in flight is significant to climb and cruising performance. This requires a higher AOA (Angle of Attack) of the wing, which results in more drag and, in turn, produces a higher stalling speed.
How are Scatterplots and correlations related to each other?
A scatterplot displays the strength, direction, and form of the relationship between two quantitative variables. A correlation coefficient measures the strength of that relationship. The correlation r measures the strength of the linear relationship between two quantitative variables.
What is the significance of a correlation coefficient?
The Statistical Significance of Correlation Coefficients: Correlation coefficients have a probability (p-value), which shows the probability that the relationship between the two variables is equal to zero (null hypotheses; no relationship). Strong correlations have low p-values because the probability that they have no relationship is very low.
Why do correlation coefficients have a low p value?
Correlation coefficients have a probability (p-value), which shows the probability that the relationship between the two variables is equal to zero (null hypotheses; no relationship). Strong correlations have low p-values because the probability that they have no relationship is very low.
Which is the strongest relationship between two variables?
The strongest linear relationship occurs when the slope is 1. This means that when one variable increases by one, the other variable also increases by the same amount. This line is at a 45 degree angle. The strength of the relationship between two variables is a crucial piece of information.
