Solve the problem. A ball is kicked upward with an initial velocity of 32 feet per second. The ball's height, h (in feet), from the ground is
modeled by h =-161+ 326. Where t is measured in seconds. How much time does the ball take to reach its highest
point? What is its height at this point?
a. 2 sec; 16 ft
c. 1 sec; 32 ft
b. 1 sec; 16 ft
d. 2 sec; 48 ft

Use the given degree of confidence and sample data to construct a confidence interval for the population mean mu . assume that the population has a normal distribution. a laboratory tested twelve chicken eggs and found that the mean amount of cholesterol was 185 milligrams with sequals 17.6 milligrams. a confidence interval of 173.8 mgless than muless than 196.2 mg is constructed for the true mean cholesterol content of all such eggs. it was assumed that the population has a normal distribution. what confidence level does this interval represent?
