Problem #1 A large warehouse has five temperature sensors located in five different places. Each sensor circuit is indicated as the figure below, where a DC current source circulates through a temperature-variable- resistance. Tk is the temperature in Celsius at the sensor in a given location; Tref is the reference temperature that each sensor has been calibrated. Assume for this problem that Tref 27 °C. Therefore, each sensor will provide a positive-voltage for temperatures greater than the reference, on the...

7. Suppose the average temperature for the local area during summer was previously known to be 24 degrees Celsius. A local scientist believes that there has been an increase in average temperature from 1996 to 2000, and argues that the average temperature during this period was significantly different from 21 degrees Celsius. The average temperatures during summer recorded from 1996 to 2000 are given as: 25, 27, 22, 27, 23. Performa two-sided t-test for the null hypothesis that Ho :...
