Question

Consider two binomial distributions, each have n=15 trials. The first distribution has the probability of success of each trial with p1=0.80 and the second distribution has the probability of success of each trial with p2=0.24. What do you observe about these two binomial distributions?

Select one:

a. The first binomial distribution will have a lower expected value than the second binomial distribution.

b. The shape of the first binomial distribution is skewed right, while the second binomial distribution is skewed left.

c. The shape of the first binomial distribution is skewed left, while the second binomial distribution is skewed right.

d. Adding all the individual probabilities for each binomial distribution will not add up to 1.

Answer #1

a. In a binomial distribution with 9 trials and a success
probability of 0.4, what would be the probability of a success on
every trial? Round to 4 decimal places.
b. In a binomial distribution with 12 trials and a success
probability of 0.6, what would be the probability of a success on
every trial? Round to 4 decimal places.
c. A binomial distribution has a success probability of 0.7, and
10 trials. What is the probability (rounded to 4...

For one binomial experiment, n1 = 75 binomial trials produced r1
= 30 successes. For a second independent binomial experiment, n2 =
100 binomial trials produced r2 = 50 successes. At the 5% level of
significance, test the claim that the probabilities of success for
the two binomial experiments differ. (a) Compute the pooled
probability of success for the two experiments. (Round your answer
to three decimal places.) (b) Check Requirements: What distribution
does the sample test statistic follow? Explain....

A binomial experiment consists of 800 trials. The probability of
success for each trial is 0.4. What is the probability of obtaining
300?-325 ?successes? Approximate the probability using a normal
distribution.? (This binomial experiment easily passes the?
rule-of-thumb test for approximating a binomial distribution using
a normal? distribution, as you can check. When computing the?
probability, adjust the given interval by extending the range by
0.5 on each? side.)

The main difference between hypergeometric and binomial
distributions is that, with the hypergeometric distribution, the
_____.
Select one:
a. trials are independent of each other
b. probability of success must be less than .5
c. probability of success changes from trial to trial
d. random variable is continuous

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 μ and standard deviation
σ. Also, use the range rule of thumb to find the minimum usual
value μ−2σ and the maximum usual value μ+2σ.
n=1405, p= 2 / 5

Consider two independent binomial experiments. In the first one,
40 trials had 15 successes. In the second one, 60 trials had 6
successes. Find a 95% confidence interval for p1 - p2.
A. 0.112 to 0.438
B. 0.097 to 0.453
C. 0.107 to 0.443
D. 0.100 to 0.450
