Start the Sound (uses Java) simulation (opens in a new window). Select the Measure" tab at the top left corner of your simulation window. Set the frequency to 200 Hz (once you click on the frequency button you can use the left and right arrow keys on your keyboard to decrease/increase the frequency to the desired value). Also set the amplitude to maximum. The waves are very now well defined. Pause the simulation. There are two blue lines that you...

You work as a technical engineer in a company that designs and installs sound systeins, such as speakers for large halls and open spaces. The company manager has assigned you to design a new sound system for a stadiun, and asked you to make a technical report explaining some preliminary studies on the behaviour of sound waves. Task 1: A When we are designing the sound levels to...

1. (55 points) The investigators are interested in asses the relationship between Systolic Blood Pressure (SBP) in mm Hg and Age in years among Hypertensive Patients. Specif- ically, whether a patient's SBP can be predicted from his or her age. They selected n=122 patients at random from a medical record database in a hospital. Assume that the simple linear regression model is appropriate. The following table shows regression output of a simple linear regression model relating the SBP to the...
