7. Billy is comparing gasoline prices at two different gas stations. At the first gas station, the equation c=2.80g gives the relationship between g, the number of
gallons of gasoline, and c, the total cost, in dollars.
At the second gas station, the cost of 2.5 gallons of gasoline is $8.30, and the cost of 5 gallons of
gasoline is $16.60.

How much money, per gallon, would Billy save by going to the less expensive gas station?
Explain why your solution makes sense.

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.
