Question Use a graphing calculator to graph the function. Then use the graph to determine the number of turning
points and the number and type (global or local, but not global) of any maximum or minimum values.
f(x)=(x+2)2(x-2)(x-3)
The graph has 3 turning point(s). The function has
(select) v maximum value(s),
local minimum value(s), and
global minimum value(s).

Abottled water distributor wants to estimate the amount of water contained in 1-gallon bottles purchased from a nationally known water bottling company. the water bottling company’s specifications state that the standard deviation of the amount of water is equal to 0.02 gallon. a random sample of 50 bottles is selected, and the sample mean amount of water per 1-gallon bottle is 0.995 gallon a. construct a 99% confidence interval estimate for the popula-tion mean amount of water included in a 1-gallon bottle. b. on the basis of these results, do you think that the distributor has a right to complain to the water bottling company? why? c. must you assume that the population amount of water per bottle is normally distributed here? explain. d. construct a 95% confidence interval estimate. how does this change your answer to (b)?
