A company surveyed 2,600 North American airline passengers and reported that approximately 60% said that they carry a smartphone when they travel. Suppose that the actual percentage is 60%. Consider randomly selecting tenpassengers and define the random variable x to be the number of the ten selected passengers who travel with a smartphone. The probability distribution of x is the binomial distribution with n-10 and p=0.6. (Round your answers to threedecimal places.)(a) Calculate p(5).P(5) = 246USE SALT(b) Calculate P(x ≤7).P(X ≤7) =(c) Calculate the probability that more than half of the selected passengers travel with a smartphone.

Regifting is defined as the act of taking a gift that has been given to you and presenting it as a gift to someone else. According to survey conducted by a credit card company regarding consumer spending, 81% of the respondents felt that it was socially acceptable to regift during the holiday season (big sigh of relief). Suppose a random sample of 10 holiday shoppers was selected. Complete parts a through d. a. What is the probability that 9 shoppers from this sample felt that regifting was socially acceptable? The probability is. (Type an integer or decimal rounded to four decimal places as needed.) b. What is the probability that more than 7 shoppers from this sample felt that regifting was socially acceptable? The probability is. (Type an integer or decimal rounded to four decimal places as needed.) c. What is the probability that fewer than 10 shoppers from this sample felt that regifting was socially acceptable? The probability is (Type an integer or decimal rounded to four…
Find the mean of the given probability distribution. A police department reports that the probabilities that 0,1,2 and 3 burglaries will be reported in a given day are 0.48,0.41,0.10,and 0.01 respectively.
A crate contains 50 led light of which 5 are defective and 45 are not. A Quality Control Inspector randomly samples 12 led light without replacement. Let X be the number of defective led light selected. Find the probability that less than 2 led light are defective. Determine the probability distribution to solve this problem.
A large insurance company indicates that 78% of the policy holders have at least one health issues and 22% do not health issues. Let Y1 be a random variable defined as Y1 = 0, if the policy holder does not have any health issues; Y1 = 1, if the if the policy holder have health issues. Write the probability distribution of Y1, E(Y1) and Var(Y1).
In the probability distribution to the right, the random variable X represents the number of marriages an individual aged 15 years or older has been involved in. Complete parts (a) through (f) below. Describe the shape of the distribution. The distribution is multimodal and is skewed right. (c) Compute and interpret the mean of the random variable X. Hx = 0.924 marriages (Type an integer or a decimal. Do not round.) Which of the following interpretations of the mean is correct? A. If many individuals aged 15 year or older were surveyed, one would expect the mean number of marriages to be the mean of the random variable. B. The observed number of marriages will be less than the mean number of marriages for most individuals. C. The observed number of marriages will be equal to the mean number of marriages for most individuals. D. If any number of individuals aged 15 year or older were surveyed, one would expect the mean number of marriages to be the mean of the random variable. (d)…
