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: Do I need to Vacuum up pet hair, etc before I use one of these Bissell Upright Steam Cleaners. I was going to purchase a new Bagless Bissell Pet Hair removal vacuum and the aile over I saw the Bissell Pro Heat cleaners for like 100 bucks more. Can I just get rid of my vacuum and use this steam cleaner instead or do you still need to vacuum before you clean. Or can I use steam cleaners without the water now and then just like a vacuum?: You have to have both. Steam cleaners aren't designed to be vacuum cleaners. (I haven't heard of a dual purpose one yet.) You need a vacuum cleaner for weekly general cleaning in between steaming and you use the steam cleaner for cleaning every couple months or if have a particularly tough stain in carpet or a large house party to clean up after. Or just buy the vacuum cleaner and rent a steamer when you need it. Or hire Stanley Steamer to steam clean for you. The only people who really need to own a steamer and use it frequently are those with white/light carpets and lots of foot traffic and pets.

Q: s there a place that will let you rent vacuum cleaners for like a few hours or a day?: Rent okorder /
