Days after use for a party, a partially inflated helium balloon no longer floats like it once did due to helium particles leaking out of the seal. Observe the
helium atoms within the balloon in the diagram below.
Key:
Helium
particle
Direction and speed of particle
(longer arrow represents more speed)
As an experiment, a student holds the partially deflated balloon over a heating
pad to heat it up. The student notices the balloon begins to expand and when
they let go of the balloon it even floats again for a few moments before sinking
back down.

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.
