Whether a relationship between the dependant and independent variables exist? 2. As to what degree or amount of influence that each independent variables have towards the dependant variables? 3. Whether the mixture of the portfolio has strong diversification effect considering the risks of each particular instrument? Objectives Among

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

Given the secretive nature of infidelity‚ exact figures about cheating and extra-marital affairs are nearly impossible to establish. But‚ listed below are some of the most well-supported facts about cheating. All cited sources can be found on our reference page. •It is estimated that roughly 30 to 60% of all married individuals (in the United States) will engage in infidelity at some point during their marriage (see‚ Buss and Shackelford for review of this research). And these numbers are probably

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
