The distribution of the binomial random variable that counts the number of successful trials in 70, each of which have a 40% probability of failure, can be approximated by which of the following distributions?
Question 9 options:
A slightly skewed right distribution with mean of 4.2 and standard deviation of 4.1.
An approximately normal distribuiton with mean of 28 and a standard deviation of 16.8.
An approximately normal distribution with mean of 42 and standard deviation of 4.1
The number of trials is not large enough to make a determination.
A slightly skewed right distribution with mean of 28 and a standard deviation of 16.8.
