- 6.1 The Standard Normal Distribution 1. Fill in the blanks using both our textbook and Lumen textbook. 2. A normal distribution is a continuous probability density function used to model the probability distribution of a random variable. The functions of all normal distributions are already defined: f (x) = So, every normal distribution is completely determined by the two parameters . and ., which are called the mean and the standard deviation. 3. If X - N(3, 1), then P(X = 4) = 0 and P(X < 4) = P(X < 4) because every normal distribution function is a probability density function of a continuous random variable. 4. When X N(u, 0), a probability P(a < X < b) is given as the area between the graph and the x-axis over [a, b]. 5. One way of using normal distribution modeling: For a random variable whose mean and standard deviation are known, we assume that the random variable fits the normal distribution with the same mean and standard deviation. Then, we use the normal distribution to…arrow_forward2 x = 1,2,3,4 f(x) = otherwise So that the variable x represents the quantity produced of dates annually and in hundreds of tons in the Iraqi company and the marketing of dates, which is subject to the following probability mass functionYou want to find: a.

- 4. Sixteen-ounce boxes of shredded wheat cereal packed automatically by machine are sometimes over- weight and sometimes underweight. The actual weight in ounces over or under 16 is a random variable X whose probability density is f(x) = c(4- x²) for -2 < x < 2, and 0 elsewhere. Negative values pertain to ounces under 16. Determine the constant c, and then find the probability that a box of cereal will be (a) more than one ounce underweight.arrow_forward11.
