A rocket motor is manufactured by bonding together two types of propellants, anigniter and a sustainer. The shear strength of the bond (y) is thought to be a linearfunction of the age of the propellant (x) when the motor is cast. Twenty observationare shown in the following table.Observation StrengthAgeObservation StrengthAgeNumber(psi)(weeks)Number(psi)(weeks)2178.715.8|112165.214.41678.1525.4122399.552.823167.5131779.8232061.318142336.75102207.56.5151765.3221808.319.4162053.5211784.724.3%3D172414.45.5825751.5182200.512.59.2357.98.33D192654.22.51.2. a. Fit a straight line by the method of least squares. Proved the slope, intercept andthe R2.b. Does the age of the propellant appear to contribute any information to theprediction of shear strength of the bond? Test at the 1% level of significance. Providethe complete Regression Analysis.c.

. 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.
