A spinner has 3 equal sections that are labeled 1,2, and 3. If the spinner spins twice, find the sum of the two numbers it lands on. Let X be the random variable that represents the sum of the two numbers. a. List all sample spaces and identify how many they are. b. Let X be the random variable that represents the sum of two numbers. What are the possible values of X? c. llustrate a probability distribution for a random variable X.

Construct a tree diagram and sample space for the outcomes of the experiment. Define the probability distribution with X=number of Pepsi selections of an outcome.Calculate the mean (expected value) and standard deviation of the distribution. Interpret the meaning of the mean and standard deviation.

The accompanying table describes results from groups of 8 births from 8 different sets of parents. The random variable x represents the number of girls among 8 children. Complete parts (a) through (d) below. E Click the icon to view the table, a. Find the probability of getting exactly 1 girl in 8 births. (Type an integer or a decimal. Do not round.) Probability distribution for x b. Find the probability of getting 1 or fewer girls in 8 births. Number of Girls x (Type an integer or a decimal. Do not round.) P(x) 0.002 0.019 0.119 c. Which probability is relevant for determining whether 1 is a significantly low number of girls in 8 births: the result from part (a) or part (b)? 1 O A. Since the probability of getting more than 1 girl is the complement of the result from part (b), this is the relevant probability. 3 0.189 O B. Since the probability of getting 1 girl is the result from part (a), this is the relevant probability. 0.342 5 0.189 OC. Since the probability of getting 0 girls is…

Does the new training program appear to be more effective than the older training program in lowering the weight of its new prospects?

Determine whether the random variable x is discrete or continuous. Explain. Let x represent the distance a baseball travels in the air after being hit. Choose the correct answer below. O A. The random variable is discrete, because it has an uncountable number of possible outcomes. O B. The random variable is continuous, because it has an uncountable number of possible outcomes. O C. The random variable ks discrete, because it has a countable number of possible outcomes. D. The random variable is continuous, because it has a countable number of possible outcomes.
