6. A company produces laptops. Their products have 1 or 2 or 3 USB ports. The proportionof laptops based on the number of USB ports on them is given by the following pmf:p(k) = C (4 – k)³; k = 1, 2,3 (k is the number of USB ports on the laptop)Note: p(1), p(2) and p(3) are the proportion of laptops with one, two and three USB ports,respectively.a. What is the value of the constant C?b. Let the random variable X be the number of USB ports on a randomly selected laptop.What is the mean of X?c. What is the variance of X?

Quit smoking: A recent study reported that in a sample of 234 European-American HIV-positive smokers, 105 of them had used a nicotine patch to try to quit smoking, and in a sample of 81 Hispanic-American HIV-positive smokers, 25 had used a nicotine patch. Can you conclude that the proportion of patch users is greater among European-Americans? Let p₁ denote the proportion of European-Americans who used the patch. Use the a=0.01 level of significance.

ge 2: Has the proportion of Americans that are "20-somethings" decreased? According to the US Census Bureau, 14.8% of Americans living in 2004 were "20- somethings" (between ages 20 and 29). You take a random sample of 500 Americans and find that 59 of them fall in this age range. Has the proportion of Americans ages 20-29 decreased from what it was in 2004? for this problem (z-test or t-test).

Q8 A desk lamp produced by DavidLee Company was found to be defective (D). There are three factories (A, B, C) where such desk lamps are manufactured. A Quality Control Manager (QCM) is responsible for investigating the source of found defects. This is what the QCM knows about the company's desk lamp production and the possible source of defects: Factory A B с % of Total Production 25%, or P(A) = 0.25 35%, or P(B) = 0.35 40%, or P(C)=0.40 % of defective 3.5%, or P(D/A) =0.035 4.5%, or P(D/B) = 0.045 6.5%, or P(D/C) = 0.065 If 100 products are randomly selected from these three factories, how many defects will be found?
When you post a picture on social media, it seems like your friends randomly "like" the picture. Independent of the quality or the humor of the photo, there seems to be a 25.7% chance of the picture being "liked" for any given picture. Let X represent the number of pictures you post until one is "liked." (X represents the photo number that is actually liked.) Find: P(X>10)
Victims of Violence A random survey of 85 women who were victims of violence found that 28 were attacked by relatives. A random survey of 46 men found that 5 were attacked by relatives. At a=0.10, can it be shown that the percentage of women who were attacked by relatives is greater than the percentage of men who were attacked by relatives? Use p₁ for the proportion of women who were attacked by relatives. Use the P-value method with tables. Part: 0 / 5
