X has a binomial distribution with number of trials 10 and success probability 0.65. What is the expected value of X?
Group of answer choices
A- 65.00
B- 6.50
C- 0.35
D- 7.00
Solution
Given that ,
n = 10
p = 0.65
Mean = = n * p
= 10 * 0.65 = 6.50
Mean = = 6.50
option B is correct

Question 3 Consider a binomial distribution with a success probability of p = 0.65 and repeated 100 times. What is the normal distribution that approximates this binomial distribution? Use the approximation to find the probability that the number of successes is between 60 and 70 in the 100 repetitions. Next consider the same binomial distribution except that it is repeated 1,000 times. What is the normal distribution that approximates this binomial distribution with 1,000 repetitions? Use the approximation to find...
