An Experiment Was Performed on a Certain Metal to Determine

question 85

Essay

An experiment was performed on a certain metal to determine if the strength is a function of heating time.Partial results based on a sample of 10 metal sheets are given below.The simple linear regression equation is

= 1 + 1X.The time is in minutes,the strength is measured in pounds per square inch,MSE = 0.5,
= 30,and
= 104.Determine the 95 percent confidence interval for the average strength of a metal sheet when the average heating time is 2.5 minutes.

Identify the main factors contributing to the severity of an earthquake's impact.

Understand the role of subduction zones and mid-ocean ridges in earthquake activity.

Understand the formation and identification of fault scarps.

Recognize the various causes of earthquakes including natural and human-induced factors.
