Hector says that the expression will always have the opposite sign as p for all values of p (positive, negative, and 0). Is he correct? Why or why not?
1.No, will always have the opposite sign as p except when p = 0.

2. Yes, ” will always have the opposite sign as p because if p is positive is negative, and if p is negative. ” is positive.

3.No, will always have the same sign as p.

4.Yes, will always have the opposite sign as p because p is positive and when divided by a negative number, the result is negative.

X+ y = 5 ; x - y =3 solve using linear combination

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.

Ineed no it anyone can see this
