The manufacturer of a certain electronic component claims that they are designed to last just slightly more than 4 years because they believe that customers typically replace their device before then. Based on information provided by the company, the components should last a mean of 4.24 years with a standard deviation of 0.45 years. For this scenario, assume the lifespans of this component follow a normal distribution.

1. The company offers a warranty for this component that allows customers to return for a refund it if it fails in less than 4 years. What is the probability that a randomly chosen component will last less than 4 years?

2.The company considers a component to be “successful” if it lasts longer than the warranty period before failing. They estimate that about 70.3% of components last more than 4 years. They find a random group of 10 components that were sold and count the number of them which were “successful,” lasting more than 4 years.

What is the probability that at least 8 of these components will last more than 4 years?

how do you post a T account given this information: 1-Dec Began business by depositing $7500 in a bank account in the name of the company in exchange for 750 shares of $10 per share common stock. 1-Dec Paid the rent for the current month, $650 . 1-Dec Paid the premium on a one-year insurance policy, $840 . 1-Dec Purchased Equipment for $3600 cash. 5-Dec Purchased office supplies from XYZ Company on account, $300 . 15-Dec Provided services to customers for $6000 cash. 16-Dec Provided service to customers ABC Inc. on account, $3400 . 21-Dec Received $1800 cash from ABC Inc., customer on account. 23-Dec Paid $170 to XYZ company for supplies purchased on account on December 5 . 28-Dec Paid wages for the period December 1 through December 28, $5040 . 30-Dec Declared and paid dividend to stockholders $200 .

Research conducted by Worldwide, Inc., a manufacturer of laptop computers, shows that potential laptop customers (i.e., “buyers”) differ in the importance that they attach to the following two laptop features:   (1) that the laptop include a solid state drive (i.e., SSD), and (2) that the laptop include a high resolution screen. A sample of five representative (prospective) customers of Worldwide reveals the following set of preferences for these attributes/benefits (the data are comma-delimited):

1, 6,    8

2, 3,     4

3, 4,     1

4, 4,     8

5, 5.5, 7       (this is not a typo: the x value for customer #5 is 5 ½)

where:

                  (1) the measurement scale is continuous, and ranges from 1=very unimportant to

     10=very important

                  (2) the first entry in a row is the respondent i.d. number

                  (3) the second entry (x-axis) is the importance weight attached to “includes a SSD”

                  (4) the third entry (y-axis) is the importance weight attached to “includes a high resolution

     screen”

For Question #1, parts (a) through (h) below, perform a k-means cluster analysis of the Worldwide data. For purposes of this question, set k= 2, and use the point (3,5) as initial centroid #1 and the point (6,1) as initial centroid #2. Perform all numeric calculations to 3 decimal places of precision (e.g., 8.352).

(1a) Which customers (i.e., “buyers”) are assigned to starting centroid #1, and what is the Euclidean distance between each of these customers and starting centroid #1? In your answer clearly indicate each customer’s id, and the Euclidean distance (to 3 decimal places) between the customer and starting (i.e., initial) centroid #1.

                                    Buyer id: _________          Distance: ____________

                                    Buyer id: _________          Distance: ____________

                                    Buyer id: _________          Distance: ____________

                                    Buyer id: _________          Distance: ____________

                                    Buyer id: _________          Distance: ____________

                  (Note: here, and below, complete for as many customers as appropriate)

(1b) Which customers are assigned to starting centroid #2, and what is the Euclidean distance between each of these customers and starting centroid #2? In your answer clearly indicate each customer’s id, and the Euclidean distance (to 3 decimal places) between the customer and starting centroid #2.

Buyer id: _________          Distance: ____________       

                                    Buyer id: _________          Distance: ____________       

                                    Buyer id: _________          Distance: ____________

                                    Buyer id: _________          Distance: ____________

                                    Buyer id: _________          Distance: ____________

(1c) Following your assignment (in 1a and 1b above) of customers to the two starting centroids, what are the revised (i.e., updated) centroid values for centroid #1 and centroid #2?   (Note: you can refer to these revisions as “1^st iteration”-revised centroids)

                  1^st iteration-revised centroid #1: ___________  

                  1^st iteration-revised centroid #2: ___________  

(1d) Next, based on your answer to part (1c), and continuing the k-means clustering process, which customers should be assigned to the 1^st iteration-revised centroid #1, and what is the Euclidean distance between each of these customers and the 1^st iteration-revised centroid #1?

                                    Buyer id: _________          Distance: ____________    

                                    Buyer id: _________          Distance: ____________    

                                    Buyer id: _________          Distance: ____________

                                    Buyer id: _________          Distance: ____________

                                    Buyer id: _________          Distance: ____________

(1e) Similarly, based on your answer to part (1c), which customers should be assigned to the 1^st iteration-revised centroid #2, and what is the Euclidean distance between each of these customers and the 1^st iteration-revised centroid #2?

Buyer id: _________          Distance: ____________   

                                    Buyer id: _________          Distance: ____________   

                                    Buyer id: _________          Distance: ____________   

                                    Buyer id: _________          Distance: ____________

                                    Buyer id: _________          Distance: ____________

(1f) Based on your customer assignments in parts (1d) and (1e), what are the 2^nd iteration-revised centroid values, for centroid #1 and centroid #2?

                  2^nd iteration-revised centroid #1: ___________    

                  2^nd iteration-revised centroid #2: ___________  

(1g) Are any additional iterations needed in this k-means clustering problem? Yes or no? Why or why not?

                  ___________________________________________________________________

(1h) What is the Euclidean distance between the final cluster centroids (i.e., the 2^nd iteration-revised centers)?

                  Distance = _______________
