Let x be a continuous random variable that is normally distributed with mean u = 26 and standard deviation o =2. Using the accompanying standard normal distribution table, find P(28

Let x be a random variable representing dividend yield of bank stocks. We may assume that x has a normal distribution with ? = 1.8%. A random sample of 10 bank stocks gave the following yields (in percents).5.7 4.8 6.0 4.9 4.0 3.4 6.5 7.1 5.3 6.1 I need help with sketching  the distribution and (d) and (e)

Assume that x has a normal distribution with the specified mean and standard deviation. Find the indicated probability. (Enter a number. Round your answer to four decimal places.) μ = 28; σ = 3.6 P(x ≥ 30) =

Assume that x has a normal distribution with the specified mean and standard deviation. Find the indicated probability. (Round your answer to four decimal places.)   μ = 15.2; σ = 3.7 P(10 ≤ x ≤ 26) =

A normal distribution with a mean of O and a standard deviation of 1 is called O a probability density function. O a standard normal distribution. O an ordinary normal curve. none of the other statements is correct.
