A rocket motor is manufactured by bonding together two types of propellants, an igniter and a sustainer. The shear strength of the bond (?) is thought to be a linear function of the age of the propellant (?) when the motor is cast. Based on the provided observations:

Strength (psi) Age (week)
2158.7 15.5
1678.15 23.75
2316 8
2061.3 17
2207.5 5
1708.3 19
1784.7 24
2575 2.5
2357.9 7.5
2277.7 11
2165.2 13
2399.55 3.75
1779.8 25
2336.75 9.75
1765.3 22
2053.5 18
2414.4 6
2200.5 12.5
2654.2 2
1753.7 21.5

In a single figure, show the scattered plot of the sample, the linear regression line, the 95% CI on the mean responses, and the 95% prediction intervals.

A rocket motor is manufactured by bonding together two types of propellants, an igniter and a sustainer. The shear strength of the bond y is thought to be a linear function of the age of the propellant x when the motor is cast. Twenty observations are shown in the table below. Construct a scatter plot of the data. Determine the relationship between bond strength and age of the propellant, and perform a simple linear regression analysis. Tabulate the following values....

NASA is interested in the shear strength of the bond between propellants in a rocket motor and whether it may be related to age of the propellant batch. A random sample of 20 propellant batches is collected and their shear strengths (in pounds per square inch) and ages (in weeks) are recorded. A linear regression model will be used to explore the relationship between the response (shear strength) and the predictor (age of propellant). 1. Write a simple linear regression...

The burning rates of two different solid-fuel propellants used in rocket systems are being studied. It is known that both propellants have approximately the same standard deviation of burning rate, that is 3cm/second and assume be normally distributed. Two random samples with the same sample size of 20 specimens are tested and the sample mean burning rates are 18 cm/second and 24 cm/second respectively. i. Test the hypothesis that one propellants have a higher average burning rate, using the P-value...
