Determine the indicated probability for a binomial experiment with the given number of trials n and the given success probability p. n = 15, p = 0.9, P(14)

A state lottery randomly chooses 6 balls numbered from 1 through 37 without replacement. You choose 6 numbers and purchase a lottery ticket. The random variable represents the number of matches on your ticket to the numbers drawn in the lottery. Determine whether this experiment is binomial. If so, identify a success, specify the values n, p, and q and list the possible values of the random variable x. Is the experiment binomial? OA. No, there are more than two outcomes for each trial OB. No, because the probability of success is different for each trial. OC. Yes, there are a fixed number of trials and the trials are independent of each other O D. Yes, the probability of success is the same for each trial. Identify a success. Choose the correct answer below. OA. A success is the number of matches on your ticket to the numbers drawn in the lottery. OB. A success is matching all of the numbers in the lottery. OC. A success is matching one of the numbers in the lottery. OD. The experiment…

You want to see if a card dealer is favoring one suit over another. You observe the dealer pick a card, put it back in the deck, shuffle, and then repeat the process 288 times. The results are displayed in the table below.  Use an αα = 0.10 significance level. outcome frecuency expected frequency spades 48   hearts 72   diamonds 87   clubs 81     The degrees of freedom = ______ The test-statistic for this data =______(3 decimal places) The p-value for this sample =-________( four decimal places.)   The p-value is ______α   Based on this, we should_______   Thus, the final conclusion is... There is insufficient evidence to conclude that the distribution of suits is not uniform. There is insufficient evidence to conclude that suits and cards are dependent. There is sufficient evidence to conclude that the distribution of suits is uniform. There is sufficient evidence to conclude that suits and cards are dependent. There is sufficient evidence to conclude that the…

q26 The table below lists the frequency of wins for different post positions in a horse race. A post position of 1 is closest to the inside​ rail, so that horse has the shortest distance to run.​ (Because the number of horses varies from year to​ year, only the first 10 post positions are​ included.) Use a 0.05 significance level to test the claim that the likelihood of winning is the same for the different post positions. Based on the​ result, should bettors consider the post position of a horse​ race?   Post Position 1 2 3 4 5 6 7 8 9 10   Wins 1818 1515 1212 1616 1313 66 77 1313 55 1111 Determine the null and alternative hypotheses.   Upper H 0H0​: ▼   Wins occur with equal frequency in the different post positions.

At least one post positions have a different frequency…

ook int rences American households increasingly rely on cell phones as their exclusive telephone service. It is reported that 49.2% of American households still have landline phone service. We decide to randomly call eight households and ask if the home has a landline phone. a-1. What is the random variable? The random variable is the count of the a-2. How is the random variable distributed? The random variable follows a binomial Probability 8 households that have a land line. probability distribution. N b. What is the probability that none of the households in the sampled group have landline phone service? (Round your answer to 4 decimal places.)

A machine uses electrical switches that are known to have a 3% fail rate for each use. The machine uses three switches, and each switch is independent. (a) How many outcomes are there in the sample space? 8 (b) Let x = the number of failed switches in one run of the machine. How many possible values of x are there? 4 (c) What is the probability of exactly one switch failing in one run of the machine?. 0.0847 X There is more than one way for one switch to fail in one run of the machine. (d) If the probability of no switches failing is 0.912673 and the probability of all switches failing is 0.000027, then complete the probability distribution table for x. X p(x) 0.912673 0 Need Help?
