Consider a multiple regression of Y (gas mileage) on two predictor variables X(1) (vehicle weight) and X(2) (engine type). Suppose X(2)is an indicator variable that takes the value +1, if the engine is fueled by gasoline and 0,if the engine is fueled diesel. Is there some numeric value for variable X(1) such that if X(1) is less than this value the mean fuel economy for gasoline vehicles will be lower than the mean fuel economy of the diesel vehicles, but if X(1) is greater than this value,the mean fuel economy for gasoline vehicles will be higher than the mean fuel economy of the diesel vehicles.

Yes, there is such a value.
No, no such value exists.
The question depends on the sign of the slope parameter for variable X(1)
You can only answer this question for a specific regression on a specific data set.

Imprisoned hotel heiress Paris Hilton has said she believes God has given her a new chance and she plans to stop acting dumb and put her influence to good use. “I’m not the same person I was,” Hilton told Walters. “I used to act dumb. It was an act. I am 26 years old, and that act is no longer cute. Do you believe it?

obviously there are some exceptions but on the whole the women from places like poland,latvia lithuania etc that have come over to britain are far better looking than british women and have far better bodies, is it because they eat healthier and try to stay slim compared with the british females who live on fast food diets and are caked in makeup to hide their blemishes? i was just wonering the reason behind this fact? obviously im going to get some nasty replies to this from some jealous overweight types but on the whole this is a fact and im not the only bloke to have noticed this.

c)THIS IS THE WORST GUY EVER!!! he made fun of me and called me a rat in front of the whole class. i really really hated him and being nice was the only excuse he had for being mean to me.

I have a 250GB external USB hard drive. It came formatted to the FAT32 filesystem, but I need to store files over 4GB on it. My question is, does anyone see any problem in converting the drive to the NTFS file system?

Several years ago we upgraded my family's PC from Windows ME to XP and I was able to convert the computer's C:\ drive from FAT32 to NTFS in place with the CONVERT DOS command, without losing any data. Will it work converting my external USB hard drive this way? Will it hurt anything?

Thanks.

I bought a large regular camp trunk at a yard sale, and it was open, but when I got home it had closed and locked itself. I do not have the key. The lock is a key lock in which a flat metal loop on the top is attactched with a hinge to the base of the trunk. Is there any way, without destroying the lock, to open the trunk?

an ex got back in touch recently, and wanted to chat. He didn´t give me much time to make other arrangements so I couldn´t meet him as I had to go to work. I haven´t heard from him since, even though I have sent him a message to say that my reason was geuine, and that I would have met him if I wasn´t at work.

I really feel that he has taken the mickey out of me again, and seems to be dangling a carrot, then taking it away.

Should i call him and tell him that I think that he is being unreasonable and that i don´t appreciate the way that he keeps playing with my feelings or should i just leave it and walk away. I think that he should know that he is hurting me again, and that i don´t like it.

What do you guys reckon?

She seems really sweet she alwasy nice has a smile on her face if you watched the simple life she was sweet to the children the family she dosent fight people she dosent go off on "diva Rampages" like Lindsay Lohan and Naomi Campbell and curse and fight people. Beside un occasional barr fight she seems really sweet and down to earth ..

Are people jealous because she pretty tall thin rich and fabulous because she didnt do anything to anyone..

And she defenitly isnt stuck up if that were the case she wouldnt have done the simple life and lived with "pooor" people and she wouldn't be giving money to AIDS funds and she insnt snobby shes always nice bublly and just lovin life shes a sweet girl why is she so hated. Now Nicole was the loud mouth always cursing people out making wise cracks etc..

And for the women out there that r just jealous dont come off with the I hate her because shes a slutt ....

or because of the sex tape stuff ..

What a woman or man does in there bedroom ...
