Textbook Question

Chapter 12.1, Problem 53E

Work the given exercises. (See Examples 5 and 9.)

Baseball Toss You stand on a hotel balcony 48 feet above the ground and Iob a baseball directly upward. You miss your catch as the ball comes down, so it falls to the vacant parking lot below. The height of the ball (in feet above the ground) after tseconds is given by

h ( t ) =-16t2+32t+48 .

At what time does the ball reach its maximum height?

What is the maximum height of the ball?

At what time does the ball hit the ground? [Hint: Solve h ( t ) =0 .]

What is the velocity of the ball when it hits the ground (this is called the impact velocity)?

(b) In various places in this module, data on the silver content of coins minted in the reign of the twelfth-century Byzantine king Manuel I Comnenus have been considered. The full dataset is in the Minitab file coins.mwx. The dataset includes, among others, the values of the silver content of nine coins from the first coinage (variable Coin1) and seven from the fourth coinage (variable Coin4) which was produced a number of years later. (For the purposes of this question, you can ignore the variables Coin2 and Coin3.) In particular, in Activity 8 and Exercise 2 of Computer Book B, it was argued that the silver contents in both the first and the fourth coinages can be assumed to be normally distributed. The question of interest is whether there were differences in the silver content of coins minted early and late in Manuel’s reign. You are about to investigate this question using a two-sample t-interval. (i) Using Minitab, find either the sample standard deviations of the two variables…
