A random variable represents the number of successes in 10 Bernoulli trials, each with probability of success p = 0.6. (A) Find the mean and standard deviation of the random variable. (B) Find the probability that the number of successes lies within 1 standard deviation of the mean. (A) The mean of the random variable is (The standard deviation of the random variable is approximately (B) P(# of successes lies within 1 standard deviation of the mean) ?

A random variable represents the number of successes in 10 Bernoulli trials, each with a probability of success p = 0.6. (A) Find the mean and standard deviation of the random variable. (B) Find the probability that the number of successes lies within one standard deviation of the mean. (A) The mean of the random variable is (Type an integer or a decimal) The standard deviation of the random variable is approximately (Round to three decimal places as needed) (B) P(# of successes lies within one standard deviation of the mean) (Round to three decimal places as needed)
