1. A density curve consists of a straight line segment that begins at the origin (0‚ 0) and has slope of 1. a. Sketch this density curve. What are the coordinates of the right endpoint of the segment? (Note that the right endpoint should be fixed so that the total area under the curve is 1. This is required for a valid density curve.) b. Determine the median‚ the first quartile (Q1)‚ and the third quartile (Q3). c. Relative to the median‚ where would you expect the mean of the distribution to lie

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

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

Exercise 5-57 Assume there are 23 homes in the Quail Creek area and 9 of them have a security system. Four homes are selected at random: | (a) | What is the probability all four of the selected homes have a security system? (Round your answer to 4 decimal places.) | Probability | | (b) | What is the probability none of the four selected homes have a security system?

The contingency tables and relative frequency probabilities in this exercise are based on the Springdale Shopping Survey database. Information like that gained from the two parts of this exercise could provide helpful insights into the nature of the respondents‚ their perceptions‚ and their spending behaviors. In particular‚ part 2 examines how conditional probabilities related to spending behavior might vary‚ depending on the gender of the respondent. Based on the relative frequencies for responses

Misuse of media for the sake of publicity‚ sales and promotion News and media in general play a very important role for every single one of us. In fact‚ it is the media that defines much of how we perceive the world around us. Without news and media groups‚ we will be constantly left out in the blue on a lot of information for both the important ones and the silly ones that we enjoy reading anyway. For this very reason alone‚ news and media groups carry an immense amount of responsibility to deliver
