1. For the multiple regression equation obtained in Exercise 16.13, determine the approximate
a. 95% confidence interval for the mean crispness rat- ing of pies that are baked 5.0 minutes at 300 degrees.
b. 95% prediction interval for the crispness rating of a pie that is baked 5.0 minutes at 300 degrees.
2. What is the relationship between (a) the results of the hypothesis test examining whether b3 differs sig- nificantly from zero at the 0.02 level and (b) the 98% confidence interval for f33?
3. For the multiple regression equation obtained in Exercise 16.11:
a. At the 0.05 level, is the overall regression equation significant?
b. Use the 0.05 level in concluding whether each partial regression coefficient differs significantly from zero.
c. Interpret the results of the preceding tests in the context of the variables described in that exercise.
d. Construct a 95% confidence interval for each partial regression coefficient in the population regression equation.

What is the velocity
: A two-stage rocket moves in space at a constant velocity of +4300 m/s. The two stages are then separated by a small explosive charge placed between them. Immediately after the explosion the velocity of the 1130-kg upper stage is +5810 m/s. What is..

Calculate the maximum possible motional emf in the wire
: Two students hold a long wire and rotate it across the earth's magnetic field so that the wire traces a circular path of radius 1.2 m. The motional emf produced in the rope is then measured on a voltmeter. If the angular frequency of rotation is w..
