The binomial distribution only applies to flipping coins and not to real life situations.
Indicate whether the statement is true or false
P + Q = 1.
Indicate whether the statement is true or false
The binomial distribution requires that the P and Q do not change from trial-to-trial.
Indicate whether the statement is true or false
The binomial distribution can be used when there are three outcomes on each trial.
Indicate whether the statement is true or false
The binomial distribution is a discrete distribution.
Indicate whether the statement is true or false
The binomial distribution is always symmetrical.
Indicate whether the statement is true or false
The binomial distribution only applies to situations where P = 0.50.
Indicate whether the statement is true or false
Evaluated over a large number of pitches, a varsity women softball pitcher threw 1400 strikes and 600 balls. Assuming things remain the same, what is the probability she will throw at least 35 strikes in her next 40 pitches. Assume independence between throws.
a. 0.0427 c. 0.0001
b. 0.0418 d. 0.0078
In solving a binomial problem, if the evaluation required only finding the probability of all P events, and N = 40, evaluating P40 would be more accurate than using the normal approximation. Assume no rounding.
a. T
b. F
c. It depends on the value of P
d. if P = Q = .50, the normal approximation would be more accurate.
Your introductory psychology class has 189 males and 261 females. If you randomly sample 40 of these classmates, what is the probability you will get at least 32 females?
a. 0.0049 c. 0.0048
b. 0.0025 d. 0.0024
