- Which is not a criterion for a binomial probability experiment Group of answer choices # of trials are known before hand Trials are independent Probability of success varies from trial to trial None of the aboveCan you help meSuppose that Dietitians recently recommended a 400 cal per meal and take her children of the age of the data set. To see if both groups adhere to the guideline follow the steps to develop and test a statistical hypothesis. Test to see if us groups means are different from 400 calories. You have two data sets so you'll be completing the process twice. Use 0.05 as a level of significance and make sure to report any important statistic with your results (e.g., mean of each group, standard deviation of each group, test stastistic (are you using t or z?), rejection region and p value).

- K Five males with an X-linked genetic disorder have one child each. The random variable x is the number of children among the five who inherit the X-linked genetic disorder. Determine whether a probability distribution is given. If a probability distribution is given, find its mean and standard deviation. If a probability distribution is not given, identify the requirements that are not satisfied. *** Does the table show a probability distribution? Select all that apply. A. Yes, the table shows a probability distribution. B. No, not every probability is between 0 and 1 inclusive. C. No, the random variable x is categorical instead of numerical. X P(x) 0 0.034 1 0.146 2 0.320 3 0.320 4 0.146 5 0.034 D. No, the random variable x's number values are not associated with probabilities. E. No, the sum of all the probabilities is not equal to 1.

- Determine whether the random variable X has a binomial distribution. If it does, state the number of trials n. If it does not, explain why not. A fair coin is lipped 5 times. Let X be the number of times the coin lands Tails. Does hovaaoes not have Part 1 of 2 The random variable does not have abinomial distribution. Part: 1/2 Part 2 of 2 The number of trials isQ3: fill in the blank for all parts for this questiondetermine whether the random variable X has a binomial distribution. If it does state the number of trials n. If it does not, explain why not. Twenty students are randomly chosen from a math class of 70 students. Let X be the total number of student absences. Part 1 The random variable -does -does not have a binomial distribution Part 2 Choose the statement that explains why X does not have a binomial distribution, more than one may apply -The Number of trials is not fixed -There are more than two possible outcomes for each trial -The probability of success is not the same for each trial -The trials are not independent -X does not represent the number of successes that occur
- Match n= 4, n = 8, n = 12 with the correct graph. Each histogram shown below represents part of a binomial distribution. Each distribution has the same probability of success p but different numbers of trials n. AP(x) 0.40- AP(x) 0.40- 0.30- 0.20- 0.10- 0.00 (a) 0.30- 0.20- 0.10- 0.00 0 369 12 0 369 12 (b) AP(x) 0.40- 0.30- 0.20- 0.10 Histogram (a) has the number of trials n = Histogram (b) has the number of trials n = Histogram (c) has the number of trials n = What happens as the value of n increases and the probability of success remains the same? OA. As n increases, the distribution becomes more skewed right. O B. As n increases, the distribution becomes more skewed left. OC. As n increases, the distribution becomes more symmetric. Click to select your answer.K A poll reported that 66% of adults were satisfied with the job the major airlines were doing. Suppose 15 adults are selected at random and the number who are satisfied is recorded. Complete parts (a) through (e) below. A. This is a binomial experiment because there are two mutually exclusive outcomes for each trial, there is a fixed number of trials, the outcome of one trial does not affect the outcome of another, and the probability of success changes in each trial. OB. This is a binomial experiment because there are three mutually exclusive outcomes for each trial, there is a fixed number of trials, the outcome of one trial does not affect the outcome of another, and the probability of success is the same for each trial. OC. This is a binomial experiment because there are two mutually exclusive outcomes for each trial, there is a random number of trials, the outcome of one trial does not affect the outcome of another, and the probability of success is the same for each trial. O.…Determine whether the given procedure results in a binomial distribution. If it is not binomial, identify the requirements that are not satisfied. Determining whether each of 50 mp3 players is acceptable or defective Choose the correct answer below. A. Yes, because all 4 requirements are satisfied. B. No, because there are more than two possible outcomes and the trials are not independent. C. No, because there are more than two possible outcomes. D. No, because the probability of success does not remain the same in all trials.
