Engineers at an oil refinery find out how easily gasoline evaporates by measuring its vapor pressure. as they make gasoline, they need to determine whether its vapor pressure is high enough. the standard deviation of the vapor pressure of the gasoline made by the refinery is always 0.03 (pounds per square inch). which hypothesis test would be most appropriate for this task?
question options:
a. one sample z-test
b. one sample t-test
c. paired-samples t-test
d. two sample t-test

How does the graph of g(x)=βxββ3 differ from the graph of f(x)=βxβ? the graph of g(x)=βxββ3 is the graph of f(x)=βxβ shifted right 3 units. the graph of g(x)=βxββ3 is the graph of f(x)=βxβ shifted up 3 units. the graph of g(x)=βxββ3 is the graph of f(x)=βxβ shifted down 3 units. the graph of g(x)=βxββ3 is the graph of f(x)=βxβ shifted left 3 units.
