Quantitative analysis

Adjust issue 16 in segment 4.2 of your content, including drawing markers from a container of markers with ink and markers without ink. Expect that the case contains 19 markers: 14 that contain ink and 5 that don't contain ink. An example of 8 markers is chosen and an irregular variable Y is characterized as the quantity of markers chose which don't have ink

What number of various qualities are workable for the irregular variable Y?

Fill in the table underneath to finish the likelihood thickness work. Be sure to list the upsides of Y in rising request.

The mean period of time needed to play out a specific errand on a mechanical production system has been set up at 15.5 minutes. A

arbitrary example of 9 representatives is shown another technique. After the preparation time frame, the normal time these 9 representativesl

take to play out the undertaking is 13.5 minutes with a standard deviation of 3 minutes. Do these outcomes give adequate

proof to demonstrate that the new strategy is quicker than the old? Utilize a .05 degree of importance. Accept that the occasions

needed to play out the assignment are ordinarily conveyed.

300 indistinguishable cathode beam tubes (CRTs) put into administration

At ate same time on January 1, 1976, encountered the accompanying quantities of disappointments through December 31, 1988:

Year 1983 1984 1985 1986 1987 1988

Number of disappointments 13 19 16 34 21 38

Accept that there were no disappointments before 1983.

a. In view of these information, gauge the combined dispersion work (CDF) of a CRT picked aimlessly.

Utilizing the aftereffects of section (a), gauge the likelihood that a CRT picked at

arbitrary

b. Keeps going over 5 years.

c. Keeps going over 10 years.

d. Keeps going over 12 years.

e. That has made due for a very long time comes up short in the eleventh year of activity.

The partner dignitary in the school of business at Tech will buy another duplicating machine

+8+

for the school. One model he is thinking about is the Zerox X10. The salesperson

has disclosed to him that this model will make a normal of 125,000 duplicates, with a standard deviationL

of 40,000 duplicates, prior to separating. What is the likelihood that the copier will make

200,000 duplicates prior to separating?.

Math 211 Math for Business Analysis Homework P2 Probability Density Functions [Taken from \"Brief Calculus and Mathematics for Business Analysis. 7"" ed. [ASU special edition)" by Warren} In exercises 1-12, check whether the given function is a probability density function. If a function fails to be a probability density mction, say why. 7. f(x) = i on[1,e] Refer to your earlier analysis. This time use calculus techniques to find the optimal location and prove that your result corresponds to the minimum cost. Show all steps in your analysis. Use letter symbols for all constants and do not substitute their numerical values until the end of the analysis. Complete the summary below. The cost function is C(x) = AVw +x' + B(L-x). Summary of results List in terms of A. B, w and x. Derivative of C(x): C'(x)= (in final form) Critical point: X = Call this point x = a Substitute numerical values w = 0.8 km, L = 10 km, A = $12,000 $/km, B = 10,000 $/km and list numerical values. Critical point: a = Cost: C(a) = C(x) at end points: C(left end) = C(right end) = Location for minimum cost: x = Minimum cost =Sketh the graph of the given function also address steps listed below.
