16. Use the given probability value to determine whether the sample results could easily occur by chance, then form a conclusion.A study addressed the issue of whether pregnant women can correctly predict the gender of their baby. Among 104 pregnant women, 57correctly predicted the gender of their baby. If pregnant women have no such ability, there is a 0.327 probability of getting such sampleresults by chance. What do you conclude?The probability shows that the sample results (1).(2)(1) O could notO couldhave easily occurred by chance. It appears that theresufficient evidence to conclude that pregnant women can correctly predict the gender of their baby.(2) is notislocting

Richard has just been given a 10-question multiple-choice quiz in his psychology class. Each question has five answers, of which only one is correct. Since he has not attended class recently, he doesn’t know any of the answers. What makes up a trial? What is a success? What is a failure? What are the values of n, p, and q? Assuming Richard guesses on all 10 questions, find the indicated probabilities. What is the probability that he will answer all 10 correctly. What is the probability that he will answer all 10 incorrectly. What is the probability that he will answer at least one of the questions correctly. What is the probability that he will get at most 3 correct? What is the average number(expected value) of questions Richard will answer correctly What is the standard deviation?
The problem involves empirical probability. The table shows the breakdown of 87 thousand single parents on active duty in the U.S. military in a certain year. All numbers are in thousands and rounded to the nearest thousand. Use the data in the table to find the probability that a randomly selected single parent in the U.S. military is in the army. Marine Air Army 25 Navy Corps Force Total Male Female Total 23 10 65 10 7 1 4 22 35 30 14 87 The probability that a randomly selected single parent in the U.S. military is in the Army is (Type an integer or decimal rounded to the nearest hundredth as needed.)
A recent study has shown that approximately 31.6% of Canadians are considered 'supertasters,' or people who experience the sense of taste with greater intensity than average. Consider a sample of 23 Canadians, each of whom are asked to indicate if they are a supertaster or not. Please use this information to answer the following questions.a. Suppose you know that at least 7 of the Canadians sampled are supertasters. What is the probability that exactly 15 of the Canadians sampled are supertasters?Answer:______________Round to at least FOUR digits after the decimal if necessary. b. What is the probability that the 10th Canadian sampled is the sixth person to indicate that they are a supertaster?Answer:______________Do NOT round your answer; give all the decimals.

According to the college registrar's office, 45% of students enrolled in an introductory statistics class this semester are freshmen, 20% are sophomores, 25% are juniors, and 10% are seniors. You want to determine the probability that in a random sample of five students enrolled in introductory statistics this semester, exactly two are freshmen. (a) Describe a trial. Can we model a trial as having only two outcomes? If so, what is success? What is failure? Choose one of the statements below:A. A trial consists of looking at the class status of a student enrolled in introductory statistics. Yes we can model this trial with "freshman" being a success and "any other class" as a failure.B. A trial consists of looking at the class status of a student enrolled in introductory statistics. Yes we can model this trial with "junior" being a success and "any other class" as a failure.C.
