As a construction engineer for a city, you are responsible for ensuring that the company that is providing gravel for a new road puts as much gravel in each truckload as they claim to. it has been estimated that it will take 500 truckloads of gravel to complete this road, so you plan to measure the volume of gravel in an srs of 25 trucks to make sure that the company isn't delivering less gravel per truckload than they claim. each truckload is supposed to have 20 m3 of gravel, so you will test the hypotheses 0 : 20 : 20 h versus h p a p at the d = 0.05 level.

The hypothesis are

Step-by-step explanation:

As the complete question is not given, the question is found online which is attached here.

The null and alternative hypothesis are as follows:

both graphs increase on their domain

neither graph has a y-intercept

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
