Devora tested two engines. as each engine's rotation got faster, its temperature increased at a constant rate.
the first engine's temperature (in degrees celsius) as a function of its rotation speed (in cycles per second) is given by the following table of values:
the graph of the second engine's temperature (in degrees celsius) as a function of its rotation speed (in cycles per second) is shown below.
the temperature of which engine increased more for each increase of 1 cycle per second?
choose 1

(choice a)
a
the first engine

(choice b)
b
the second engine

(choice c)
c
the temperatures of both engines increased the same
which engine was hotter when it rotated at 20 cycles per second?
choose 1

(choice a)
a
the first engine

(choice b)
b
the second engine

(choice c)
c
both engines were equally hot

Powerful women's group has claimed that men and women differ in attitudes about sexual discrimination. a group of 50 men (group 1) and 40 women (group 2) were asked if they thought sexual discrimination is a problem in the united states. of those sampled, 11 of the men and 19 of the women did believe that sexual discrimination is a problem. if the p-value turns out to be 0.035 (which is not the real value in this data set), then at = 0.05, you should fail to reject h0. at = 0.04, you should reject h0. at = 0.03, you should reject h0. none of these would be a correct statement.
