Kin 371 Chapter 5 Normal Distributions Flashcards Quizlet What's a normal distribution? a continuous probability distribution for a random variable, x. the graph of a normal distribution is called the normal curve. what're the properties of a normal distribution? the graph curves upward to the left of mew sigma and to the right of mew sigma. Many continuous variables have distributions that are bell shaped andare called approximately normally distributed variables. the normal distribution curve is bell shaped. the mean, median, and mode are equal and located at the center of the distribution. the curve is symmetrical about the mean. Chapter 5 normal distributions i. the research process (revisited) analyze the data examine data calculate descriptive statistics calculate inferential statistics ii. types of distributions a. so far (chs 1 4): b. now (chs 5 ): ch. why? to visually and subjectively describe the distribution of data for a variable how?. Normal distribution is called the normal curve. 1. the mean, median, and mode are equal. 2. the normal curve is bell shaped and symmetric about. the mean. 3. the total area under the curve is equal to one. 4. the normal curve approaches, but never touches the xaxis as it extends farther and farther away from the. mean. 5.

To complete this section of homework watch chapter five, lecture examples: 75, 76, 77, 78, and 79. 1. male heights are normally distributed with a mean of 69 inches and a standard deviation of 2.8 inches. what is the probability that a randomly selected male is 72 inches (6 ft) tall? 2. Example: suppose that the price of a slice of cheese pizza from a randomly selected restaurant in dallas, tx follows a normal(2.62, 0.16) distribution. find the probability that a slice of pizza from a randomly selected restau rant costs less than $2.25. Describe and compare the characteristics normal distribution and standard normal distribution transform scores ( x ) into z scores evaluate and interpret z scores. Practice problems on normal distributions, z scores, central limit theorem, and binomial approximations. includes solutions and examples.
