Quantitative research usually utilizes descriptive or experimental methods (Rakap‚ Snyder & Pasia‚ 2014). The descriptive method determines association between variables and the experimental method determines connectedness. Descriptive research is thought to be easier to do and is less suited to explain a connection between two variables; experimental research is usually seen as more import but more difficult to conduct (Sloman‚ 2010). The purpose of descriptive research is to observe‚ describe and

1) Suppose that an independent laboratory has tested trash bags and has found that no 30-gallon bags that are currently on the market have a mean breaking strength of 50 pounds or more. On the basis of these results‚ the producer of the new‚ improved trash bag feels sure that its 30-gallon bag will be the strongest such bag on the market if the new trash bag’s mean breaking strength can be shown to be at least 50 pounds. The mean of the sample of 40 trash bag breaking strengths in Table 1.9 is x=50

Does asymptotic mean that the normal curve gets closer and closer to the X-axis but never actually touches it? Yes‚ asymptotic means that the curve of a line will approach 0 (the x-axis)‚ but it will not touch 0 and instead will extend to infinity. In this class‚ this applies to the normal continuous distribution and is one of the 4 key characteristics of a normal continuous distribution that our text book discusses. This means that the curve of the line will extend infinitely in both the negative
