If P ( A ) = 0.45 then for any event B we have P ( A ∩ B ) ≤ 0.45
Group of answer choices
True
False
Solution:
6. Given that p = 0.17, n = 6
P(X >= 1) = P(1) + P(2) + P(3) + P(4) + P(5) + P(6)
= 0.4018 + 0.2057 + 0.0562 + 0.0086 + 0.0007 + 0.0000
= 0.6730
Binomial distribution: P(X = r) = nCr*p^r*q^(n-r)
Ex = P(X = 1) = 6C1*0.17^1*0.83^5
= 0.4018
7. option B. false.

3. The Jordan Sports Equipment Company finds that 10% of the general population is left-handed. Use the binomial table or formula (bottom) as appropriate in answering the following questions. (a) If 20 people are randomly selected, find the probability that exactly 3 of them are left-handed. (b) If 8 people are randomly selected, find the probability that at least one of them is left-handed.
In a survey of 300 people, approximately 15% of the people identified themselves as being left-handed. What are the mean, standard deviation, and shape of the distribution of thesample proportion p-hat of respondents who say they are left-handed? (3 points) Using the normal approximation without the continuity correction, sketch theprobability distribution curve for the distribution of p-hat. Shade equal areas onboth sides of the mean to show an area that represents a probability of .95,and label the upper and lower...

2. Suppose that 10% of the general population is left-handed (a) We randomly sample 20 individuals. Find the probability that fewer than 2 of them are left handed. Hint: You cannot use the normal distribution (b) we randomly sample 200 individuals. Find the probability that less than 8% of them are left handed.
s. Assume that 10% of the adult population is left-handed. If 50 adults are randomly selected, use normal approximation to find the probability that more than 12 are left-handed. Round answer to four decimal places. (4 pts)
Suppose that 12% of the population of the U.S. is left-handed. If a random sample of 130 people from the U.S. is chosen, approximate the probability that at most 14 are left-handed. Use the normal approximation to the binomial with a correction for continuity. Round your answer to at least three decimal places. Do not round any intermediate steps.

Suppose that 10% of students are left-handed. a) In a study group of 6 students, find the exact probability that at most 1 of them is left-handed. b) In a classroom of 60 students, find an approximate probability that at most 10 of them are left-handed.
NAME: 7. (15 points.) Left-handed people are more prone to accident-related injury than right-handed people Among a certain population of college students, the number of injuries X reported by a given student is a Poisson random variable; left-handers (L) report injuries at a handers (R) at a rate of 0.15 per year, 15% of the students are left-handed. rate of 0.25 per year, and right- (a) What is the probability that a randomly selected student is injured exactly twice this...
