It is desired to develop a statistical acceptance procedure for the percentage compaction of stabilized base-course layers. from a historical summary of this data, the standard deviation was found to be 3.31%. the mean value, for successfully performing layers, was also found to be 99.0%. it has been agreed that the probability for rejecting a base course whose mean compaction is 99.0% should be 2%. however, when the true mean value of the compacted stabilized course is 93.5%, the highway department would like to only have a risk of 5% associated with acceptance. based on this information, determine the number of sampling units along the rejection-acceptance mean value that would constitute the statistical quality assurance specification for this factor list any assumptions and show all your work

A1000-kg weather rocket is launched straight up. the rocket motor provides a constant acceleration for 16-s, then the motor stops. the rocket altitude 20-s after launch is 510-m. you can ignore any effects of air resistance. a. what was the rocket’s acceleration during the first 16-s? b. what is the rocket’s speed as it passes through a cloud 5100-m above the ground?

What is the acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds
