Assignment - Statistics Project Example where X1 , X2 , X3 are the three test scores and X is the final score. Assume that your test scores are (integer) values between 1 and 10 with equal probability 1/10, independently from each other. What is the probability mass function of the final score? Q6. (10) The metro train arrives at the station, always on time, near your home every quarter hour starting at 6:00 AM. You walk into the station every morning between 7:10 and 7:30 AM, with the time in this interval being a uniform random variable. The mean is the most commonly-used measure of central tendency in a distribution. The mean is valid only for interval data. Since it uses the values of all of the data points in the populations or sample, the mean is influenced by outliers that may be at the extremes of the data set. On the other hand, the median can be determined for ordinal data as well as interval data. Unlike the mean, the median is not influenced by outliers at the extremes of the data set. Q8. (10) A system consists of 3 components arranged in series. The lifetime (in days) of each component follows approximately an exponential distribution with a mean lifetime of 100 days. The lifetimes of the components are independent. Where p1(x, ï  ¬), p2(x, ï  ¬), p3(x, ï  ¬) are three independent exponential distributions in parallel. After some algebra and if we take q as any of the three independent exponential distributions, q = p1 or q = p2, q = q3, q = ï  ¬

Core Needs Addressed and Bases of Market Segmentation - Essay Example Examining the case of Lane Bryant, it is ostensible that the company is seeking to meet the basic need for clothing with their introduction of a’ new activewear line’. The workout-wear branded as Livi Active is a product that seeks to meet the clothing desires and demands of women while participating in the gym exercises or as they leave. Availing it in sizes that fit a higher percentage of its target customers has ensured this demand is met (Mahoney, 2015). This base of segmentation considers the demographic variables including age, size, education, religion, gender among others (Blythe, 2008). Considering the case of Lane Bryant’s new product, Livi Active has been initiated with clear conscious about certain variables. Gender, age and body size are the primary aspects that have been examined extensively. The product seeks to meet the demand of ladies and not any other gender. Also, the gap in terms of body sizes has been thought through before coming up with a product that suits size 12. This has been generated from the information and statistics available. Consequently, the psychological influence that drives people into having needs and wants have been considered. In this case, lifestyle is the core aspect that has informed the development of this product. In the plus-size women desire to look sharp and this makes them develop a strong need for gym wears that are designed with colors that can attract them. The bright colors are apparently the best for this. The company’s new product targets plus-size women whose body size are above size 12. The new product is to be designed brightly and fashionably for the large-bodied customers who, in the past, have not had the chance to receive such stylish clothes. Unlike the traditional system where  Lane Bryant only stylishly designed wears for medium and small size customers, the new product will incorporate the large sizes to enjoy the same.
