Based on a poll, 60% of adults believe in reincarnation. Assume that 8 adults are randomly selected, and find the indicated probability. Complete parts (a) through (d) below.a. What is the probability that exactly 7 of the selected adults believe in reincarnation? The probability that exactly 7 of the 8 adults believe in reincarnation is __.(Round to three decimal places as needed.) b. What is the probability that all of the selected adults believe in reincarnation? The probability that all of the selected adults believe in reincarnation is __.(Round to three decimal places as needed.) c. What is the probability that at least 7 of the selected adults believe in reincarnation? The probability that at least 7 of the selected adults believe in reincarnation is __. (Round to three decimal places as needed.) d. If 8 adults are randomly selected, is 7 a significantly high number who believe in reincarnation? A. No, because the probability that 7 or more of the selected adults believe in reincarnation is less than 0.05. B. Yes, because the probability that 7 or more of the selected adults believe in reincarnation is greater than 0.05. C. Yes, because the probability that 7 or more of the selected adults believe in reincarnation is less than 0.05. D. No, because the probability that 7 or more of the selected adults believe in reincarnation is greater than 0.05.
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
