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 am planning to start working for Rainbow vacuum. Any warning that I should know about? Any helpful hints? Anything?: The vacuum cleaners are hard enough to sell in a normal economy. In a lousy economy like what we have now, the job is vene more difficult. Folks don't buy a $1300 vacuum just because. They have to be fully convinced it is worth the money. It is very heavy, especially with the water in it, and you should not try to dismiss objections about carrying it up down stairs - that is really not recommended, and not to be advised because of the risk of injury. They either empty the unit of water, and refill on the second floor, or they buy a second system for the second floor - and you can double your sales! If you every find such a customer, give them a good discount on the second system, OK? Good Luck; but in case things are slow, I suggest you have another part time job ready.

Q: Hans Klobber sells vacuum cleaners. He gets to keep one eighth of his sale as a commission. How much must he sell in order to earn $1000?: He must sell $8000 because if he kept one eighth of it, he would have $1000

Q: What's the difference between vacuum and centrifugal dust collection?: Centrifugal cyclone dust cleaner, no longer need to filter system (HEPA), because of the air cleaner in the formation of the cyclone, with dust, debris, hair centrifugal force while rotating them thrown out, and the more heavy swing faster. This leads to the separation of dust, debris, and air.

Q: expression 49.94x + 27.77y + 25.82z describes the cost of producing each of the handheld vacuum cleaners. Write a polynomial in simplest: Profit = revenue - cost = 56.69X + ??y + 66.74z - (49.94x + 27.77y + 25.82z) = (56.69X - 49.94X) + (??Y - 27.77Y) + (66.74z - 25.82z) = 6.75X + ((??Y - 27.77Y) + 40.92 you did not give us the revenue for the 'y' units.

Q: I have a pug that sheds constantly and I have gone through a few vacuum cleaners.: Dyson animal vacuum cleaner is a good choice

Q: I want to buy a vacuum cleaner. So I went to OKorder and try to search for good yet cheap vacuum cleaners, and I want to buy this one:: lol yes it still hoovers! instead of going into a bag it goes into a compartment in the hoover, which when full u can take off and empty... then put it back on... works exactly the same as a bag hoover, just more convienient and easier!

Q: are canister vacuum cleaners good brands?so where are they for sale online: Some canisters vacs are good, but you will pay for a good one. On a canister, the motor is away from the dirt, you have to rely on suction, which will eventually fade as time goes by. As for an upright, the motor is on the head or closer to the dirt. When you have a motor on the head, you have a better suction, for a longer time, plus the motor will help vibrate the dirt in the carpet. idk where to find them on-line, I always go to sears, or buy a Kirby from a salesman. If you want the best canister, buy a Filter Queen or a Rainbow. If you want the best upright buy a Kirby or a Dysonex (check spelling)

Q: I want to know what do you think about a simplicity 6 series vacuum cleaners IF you own one I would like some feedback are they better then the other vacuums far as sucking power go. Thank you I also did a spell check.: it is a good choice,,everyone has there own choice
