For each of the following statements, identify whether the statement is true or false, and explain why. Please limit each response to no more than 2 sentences. a) The probability that a continuous random variable takes a specific value is 0. b) Statistical inference is the process of drawing conclusions about unknown statistics by using known parameters. c) The terms “histogram” and “bar graph” are synonyms. d) If two events A and B are independent, then there is no overlap...
8. True or False: (1 pt each) A. In a continuous probability distribution, the area underneath the density curve must be equal to 1. B. In a binomial experiment, the number of successes are fixed but the number of trials will vary. C. A standard normal distribution has mean of O and standard deviation of 1

True or False With explanation please. 1- True or false: a. If A is an event of a sample space with P(A)-P(AS), then P(A)-0.5 b. Under certain conditions, it is possible that the sum of the probabilities of all the sample points in a sample space is less than one P(A or B)-P(A)+P(B) P(A and B) P(A).P(B) by its own probability and then adding all the products together; that is P deviation of σ. If x is converted to the...

1. What is the mean of a binomial distribution with n = 8 trials and p = 0.15? 2. The area under a normal curve represents the: probability of an event occurring Z-score standard deviation mean 3. A manufacturing process outputs parts having a normal distribution with a mean of 30 cm and standard deviation of 2 cm. From a production sample of 80 parts, what proportion of the sample can be expected to fall between 28 and 32 cm?...
2. (2 True-False. Just say whether each statement is True or False – no need to justify your answer. 1. If the number of trials in the binomial distribution increases by 1 (and P equals .50), the probability of getting either of the most extreme possible outcomes (that is, 0 or N) is cut in half. 2. If the number of trials in the binomial distribution increases by 1 (and P does not equal .50), the probability of getting either of...
1. True or False: (1pt each) (T) (F) If a distribution is normal, then it is not possible to randomly select a value that is more than 4 standard deviations from the mean. (T) (F) Normal distribution is a discreet probability distribution for a random variable. (T) (F) If the variable follows a binomial distribution, then about 68 % of the variables are within 1 SD of the mean, about 95% of the variables are within +2 SD of the...
