What would be the value of the mean for a binomial distribution that 141 trials and a success probability of 0.19?

What would be the value of the mean for a binomial distribution that 186 trials and a success probability of 0.68?

What would be the value of the mean for a binomial distribution that 80 trials and a success probability of 0.49?

What would be the value of the mean for a binoial distribution that 175 trials and a success probability of 0.09?

Expert Solution

solution

Using binomial distribution,

mean and standard deviation

(A)Mean = = n * p = 141* 0.19= 26.79

Mean = =26.79

(B)

Mean = = n * p = 186* 0.68= 126.48

Mean = =126.48

(C)

Mean = = n * p = 80* 0.49= 39.2

Mean = =39.2

(D)

Mean = = n * p = 175* 0.09= 15.75

Mean = =15.75

Consider a binomial distribution of 200 trials with expected value 80 and standard deviation of about 6.9. Use the criterion that it is unusual to have data values more than 2.5 standard deviations above the mean or 2.5 standard deviations below the mean to answer the following questions. (a) Would it be unusual to have more than 120 successes out of 200 trials? Explain. Yes. 120 is more than 2.5 standard deviations above the expected value. Yes. 120 is more...

True or false. Consider a binomial distribution with 16 trials. Look at a table showing binomial probabilities for various values of p, the probability of success on a single trial. For small values of p, the distribution is skewed to the right.

Assume that a procedure yields a binomial distribution with n trials and the probability of success...

Assume that a procedure yields a binomial distribution with n trials and the probability of success for one trial is p. Use the given values of n and p to find the mean mu and standard deviation sigma. ?Also, use the range rule of thumb to find the minimum usual value mu minus 2 sigma and the maximum usual value mu plus 2 sigma. n n=1510?, p=4/ 5

Criteria for a Binomial Distribution A. The number of observation or trials is fixed. B. Each observation or trial is independent. C. For each trial, there are only two possible outcomes. A quality control expert at a large factory estimates that 10% of all batteries produced are defective. If he takes a random sample of fifteen batteries, what is the probability that exactly two are defective? A quality control expert at a large factory estimates that 10% of all the...
