Topic: **case study procedure****Question:**
A drug co. claims that more than half of those using its new allergy drug have relief. In a study 108 of 202 subjects reported relief. At the .01 significance level, is the claim true that more than half of all those using the new drug experience relief?

This appears to be a one-proportion z-test. If you have a TI-83 or TI-84 graphing calculator, use the 1-PropZTest option, found under STAT --> TESTS. Simply enter 0.5 for p0, 108 for x, 202 for n, and select >p0. When you get the results, look at the p value. If the value is less than 0.01, than the claim is true. In this case, the p value is 0.1623, clearly greater than 0.01, so the claim is not true at the 0.01 significance level. To find the p value without the calculator's test option, use the formula z = (phat - p)/(square root of p(1 - p)/n) phat = 108/202 p = 0.5 n = 202 You should get a z value of about 0.985. Then, use a z-values table or the calculator's normalcdf function to find P(z < -1.75), you should get 0.1623, which is the p value. Hopefully this is the correct procedure. Good luck.

You don't want to use Megastat for this - that would be strictly trial and error... You should know that a P% confidence interval is (usually) a number (z) of standard deviations above and below the mean: (μ-zσ,μ+zσ), so that the probability of landing in that interval is P% = Prob(μ-zσ

certainty learn, they're actual extra valid -- in that the solutions require statements of certainty and grant a huge gamble to quote sources -- than a query like this, that's only a rely of very own selection. i think of that Y/A became initially meant to be a documents-based communicate board even though it has stepped forward right into a series of mini-blogs and op-ed products, particularly. i hit upon those forms of questions exciting and, particularly situations, theory-frightening. If I even have time i will do the study although that is relaxing to study the solutions after others have carried out the artwork.

how are you able to be a Christian with out proving the existence of the writer to your self? i'm an Echatologist. and that i'm a Christian. i'm in contact approximately proving the existence of God to myself. yet have on no account been moved to get entangled in proving Christianity via His existence......... by way of fact all I might desire to do is go searching me...... Christianity is an ordinary fact. no longer an exceedingly exceedingly one granted....... (its habit could be a project for a distinctive time) i can be certain the ease of your question complicated the existence of a Christian God....... i'm no longer following the logic...... except God's existence for some reason marks a particlar sort of Christianity as be the only actual one???? And that logic could be stupid. So after examining the question's extra information persistently that's what i think of you're saying..... "Why do Christians make God right into a Christian God." whilst there are maximum of different "flavors" of God obtainable? by way of fact they suspect they comprehend wisely who he's?? My wager.

This is a question about central limit theorem. Basically what this says (in this context) is that if you performed the experiment of tossing 100 coins a large number of times, noting the number of heads in each case, then the distribution of results would approximate to the normal distribution. The binomial approximation is that the distribution will be normal with mean np and standard deviation of sqrt(np(1-p)) where n is the sample size and p is the probability. Given that n = 100 and p = 0.5, you can use a calculator such as this one: http://davidmlane.com/hyperstat/z_table.... to calculate that the approximate probability of tossing 60 or more heads is 0.02275.

nicely, perchance you ought to sit down down along with your mom and tell her precisely what you reported right here. tell her how a lot that is affecting your existence and that is an embarassing element you ought to address common. particular each and every human being farts now and again, yet you're doing it more desirable than the common human being. in case you go away the farts interior you for too lengthy it will dissatisfied your abdomen and also you completely received't sense nicely in any respect. Been there, executed that. in case you're trying this.. and then that is time to pass homestead or although and also you may't get them out, it really is something that'll help get the air out quicker. Lay down on your back, and pull up one leg at a time on your chest, and carry it there along with your fingers. it might promote the air to pop out. :) wish that enables. You coud continuously inspect gas alleviation stuff at customers Drug Mart or yet another pharmacy. in the different case, anticipate the xray. Goodluck.
