Q: I'm ready to pull my hair out.I can't seem to figure out how to use the standard normal distribution table to find Z.The question isWe want to investigate a claim about the average sound intensity of certain vacuum cleaners. Suppose the sound is a random variable having a normal distribution with a standard deviation of 3.6 dB. Specifically, we shall want to test the null hypothesis u = 75.20 against the alternative hypothesis u gt; 75.20 no the basis of measurements of the sound intensity n = 15 of these machines. If the probability of a Type I error is to be a = 0.03, what is the probability of a type II error for u = 77 dB.How do I use the normal distribution table to find a = 0.03. The only thing I know is that I have to do 1 - a.After that I can't seem to find out the rest of it. Please. Plesae just help with that.: It means like this.... In making a vacuum cleaner, since it is fairly complicated and made of many parts and does not come out exactly the same every time it is made, there are many small random effects that contribute to the amount of noise that the vacuum cleaner makes. The normal distribution is what we see whenever there are many random effects that are added together. If the same random effects apply every time, and the same measurement and sampling method is used the same time, then the distribution of the measurements will fit the normal distribution.

Q: I mean.. aren't they just vacuum cleaners for decaying dead things?: Why dont veggies get us sick? I mean we fertilize them with poop?

Q: Geddit?: I personally wouldn't make it my profession to do that, especially if you have to go door to door because people don't open their doors to anybody anymore.

Q: I need a good one that has edge cleaner, easy to maneuver, not too heave (under 20lbs) and quality. I like the bag-less type. Thanks for your input.: I okorder /

Q: Currently I use a Bissell power force. It does work well but does not pick up all hair. I know I cant complain due to the fact is was under $50. Also it is very hard to push due to have to have it on a low setting to pick up the best. Thanks in advance.: The Shark Navigator is a small, compact vacuum with features and capabilities similar to that of its full sized and more expensive counterparts. It is by no means a replacement for a Dyson or a Miele, however, at only $140.00, it is a good compromise between more expensive, more powerful units, and cheap vacuums that don't work at all. In our tests, the Navigator did a very good job of picking up pet hair. Consumers also report having a good experience with the Navigator removing pet hair. Shark has also just released the Navigator Lift-Away, which combines an upright vacuum and a canister into one neatly packaged vacuum cleaner. We are currently reviewing the Lift-Away and will have it posted soon. One final note, we have found that bagless vacuums are far superior to bagged vacuums when it comes to pet odor control. We’ve tested Oreck bagged vacuums with special odor control features and very expensive Miele pet vacuums with special odor inhibiting filters, and none of them really work. The only vacuums we’ve found that don’t have pet odor problems are bagless vacuums you can empty regularly, with washable filters that you can wash as often as necessary to control odors.

Q: ok i was going to vacuum both the carpet and hardwood but i don't know how to change the sliding thing on the bottom of the vacuum and where to put it should i just put it on hard? making sure because i dont want to ruin the hardwood Thanks!!!!!: The adjustment settings on vacuum cleaners are there so you won't ruin the roller brush on the vacuum....not the floor. What make/model of vacuum cleaner do you have? My vacuum cleaner (a Eureka Boss SmartVac) has different height levels and then 2 adjustments for using hard floors.

Q: the sound comes on, but it doesn't suck anything up and the thingy underneath (dont know the technical term) doesn't turn. it's an old vacuum( a kerby). what's wrong with it. should i try to get this one fixed or just buy a new one. are there places that fix vacuum cleaners? thanks for any info.: try cleaning the brushes under neath it. sometimes hairs and strings get wrapped around them. Check ur bag? u may have clogged suction hose. check yellow pages u might find a repair shop.

Q: It's $199 Cnd., and there's a $249 pet dust model, too. 24 cyclone tech, 17 ft. stretch hose, furniture attachments. Not to be confused with the earlier Shark models. It promises to do same job as competition twice the price, but y'know....Vacuum Cleaners.I just don't feel like doing the 'buy, try, and return' routine, so opinion from someone will be appreciated.: ummm the best vacuum in the dyson
