An train station has determined that the relationship between the number of passengers on a train and the total weight of luggage stored in the baggage compartment

An train station has determined that the relationship between the number of passengers on a train and the total weight of luggage stored in the baggage compartment can be estimated by the least squares regression equation ?=188+25?y=188+25x. Predict the weight of luggage for a flight with 33 passengers.

Answer:  pounds

Solutions

Expert Solution

The equation is y = 188 + 25x

So for x = 33, the predicted value is

y = 188 + 25 × 33

= 188 + 825

= 1013 pounds

The Airline Passenger Association studied the relationship between the number of passengers on a particular flight and the cost of the flight. It seems logical that more passengers on the flight will result in more weight and more luggage, which in turn will result in higher fuel costs. For a sample of 20 flights, the correlation between the number of passengers and total fuel cost was 0.688. State the decision rule for 0.025 significance level: H0: ρ ≤ 0; H1:...

We are interested in examining the relationship between the number of calories people consume and weight. We randomly selected 200 people and presented the data with explanatory (x) variable being the calories consumed and the response (y) variable being their weight. Regression analysis will be good for this problem because it helps us find trends in data and quantify the results. It can also help us make predictions about data. So as long as the requirements are met for inference...

A researcher has examined the relationship between the number of hours driven by long-distance truckers in a 24-hour period (X) and reaction time in seconds (Y) at the end of the 24-hour period. The relationship is approximately linear and the correlation between the two measures is +0.43. In order to assess the usefulness of the independent variable as a predictor of reaction time, the research team determined that the regression line was given by the following: Y’ = -2.5 +...
