In this course, the Python methods for hypothesis tests return two-tailed probability values. Suppose a one-tailed alternative hypothesis is used. How can you obtain a one-tailed probability value (P-Value)? Select one.       Divide the result by 4   Multiply the result by 4   Divide the result by 2   Multiply the result by 2

A bag contains 8 red marbles, 6 white marbles, and 6 blue marbles. You draw 4 marbles out at random, without replacement. Find the following probabilities and round to 4 decimal places. a. The probability that all the marbles are red is

Determine the null and alternative hypotheses. A. H0​: All outcomes are equally likely. Ha​: At least one of the probabilities is different from the others. This is the correct answer.   B. H0​: At least one of the probabilities is different from the others. Ha​: All outcomes are equally likely.   C. H0​: All frequencies are equal to 5. Ha​: All frequencies are less than 5. Your answer is not correct.   D. H0​: All frequencies are less than 5. Ha​: All frequencies are equal to 5.   Compute the value of the test​ statistic, χ2.   χ2= ​(Round to two decimal places as​ needed.)   Find the​ P-value.   P= ​(Round to three decimal places as​ needed.)   Does it appear that the loaded die behaves differently than a regular​ die?     A. Yes​, because there is sufficient evidence to reject the null hypothesis.   B. No​, because there is not sufficient evidence to reject the null hypothesis. answer is correct.   C. Yes​, because there is not…

Biologists estimate that a randomly selected baby elk has a 44% chance of surviving to adulthood. Assume this estimate is correct. Suppose researchers choose 7 baby elk at random to monitor. Let X = the number that survive to adulthood. Does this scenario describe a binomial setting? Justify your answer. This is not a binomial setting. The probability of success is not the same for each trial. This is not a binomial setting. The number of trails are not fixed in advance. This is a binomial setting and X has a binomial distribution with n = 7 and p = 0.44. This is not a binomial setting. The given scenario is not binary. This is not a binomial setting. We cannot reasonably assume that the outcomes are independent.
