i. Calculate the regression model to fit the data. ii. Predict the life time of the device for the temperature of 55oC. b. Company XYZ manufactures an electronic device to be used in a very wide temperature range. Itis known that the change of temperature will change the life time of the device. A research isconducted in which the life time is determined as a function of temperature. The following tableshows the summary of the finding.405060Temperature(Celcius)102030708090420 | 360| 280225Life time177 1184010(hours)

1. The barnacle falls off the wheel after 22.5 minutes. Use your regression equation to predict the height of the barnacle when it falls of the wheel,to the nearest tenth of a meter. 2. Determine the total time within the first rotation that the barnacle is at least 2 meters above the surface of the water, rounded to the nearest tenth of a minute
In thermodynamics, the Van der Waal's equation relates the mean pressure, p, of a substance to its molar volume v at some temperature T as follows: Chemists are interested in the curves, called isotherms, described by this equation when the temperature is held fixed, and R is a constant.

Can balloons hold more air or more water before bursting? A student purchased a large bag of 12-inch balloons. He randomly selected 10 balloons from the bag and then randomly assigned half of them to be filled with air until bursting and the other half to be filled with water until bursting. He used devices to measure the amount of air and water was dispensed until the balloons burst. Here are the data

. At wind speeds above 1000 cm/sec, significant sand–moving events begin to occur. Wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. The cyclic nature of wind and moving sand determines the shape and location of large dunes. At a test site, the prevailing direction of the wind did not change noticeably. However, the velocity did change. 75 wind speed readings gave an average velocity of x =1045 cm/sec. Based on long–term experience,  can be assumed to be 240 cm/sec Find a 99% confidence interval for the population mean wind speed at this site.
