ASHFORD UNVERSITY MAT 232 WEEK 4 ASSIGNMENT STATISTICAL LITERATURE LATEST 2023 3/4/2021 Week 4 - Assignment 1. 2. 3. Student: Date: Instructor: Course: MAT232: Statistical Literacy Assignment: Week 4 - Assignment Many states have lotteries that involve the random selection of digits 0, 1, 2, ..., 9. Is the distribution of those digits a normal distribution? Why or why not? A. No. The digits are selected randomly, so the graph of the distribution will tend to be asymmetric, not bell-shaped. B. Yes. The ten different possible digits are all equally likely, so the graph of the distribution will tend to be bell-shaped. C. No. The ten different possible digits are all equally likely, so the graph of the distribution will tend to be flat, not bell-shaped. D. Yes. The digits are selected randomly, so the graph of the distribution will tend to be bell-shaped. State whether one would expect the data set described below to be normally distributed. Explain why or why not. The measured blood sugar levels of 5,000 randomly selected adult women A. One would not expect this data set to be normally distributed. There will be many adult women with very low blood sugar levels, but only a few with high blood sugar levels, so the distribution will not be symmetric. B. One would expect this data set to be normally distributed. Such physical measurements generally tend to be normally distributed. A small number of adult women will have extremely low measurements, a small number will have extremely high measurements, and the distribution will tend to peak around the mean. C. One would not expect this data set to be normally distributed. Such physical measurements tend to have a uniform distribution because each of the values is equally likely. D. One would expect this data set to be normally distributed. There will be many adult women with very low blood sugar levels, but only a few with high blood sugar levels, so the distribution will not be symmetric. A study was conducted that resulted in the following relative frequency histogram. Determine whether or not the histogram indicates that a normal distribution could be used as a model for the variable. 1,000 2,000 3,000 4,000 5,000 0 0.2 0.4 Calories Consumed per Day Relative Frequency Choose the correct answer below. A. as a model for the variable. The histogram is not symmetric around a single peak and is not bell -shaped, so a normal distribution could not be used B. The histogram is symmetric around a single peak and bell-shaped, so a normal distribution could not be used as a model for the variable. C. The histogram is not symmetric around a single peak and is not bell-shaped, so a normal distribution could be used as a model for the variable. D. as a model for the variable. The histogram is symmetric around a single peak and bell -shaped, so a normal distribution could be used 3/4/2021 Week 4 - Assignment 4. 5. Consider the normal curve in the figure to the right, which gives relative frequencies in a distribution of men's heights. The distribution has a mean of inches and a standard deviation of inches. 69.5 2.6 height (inches) a. What is the total area under the curve? The total area under the curve is 1.00 . (Round to the nearest hundredth as needed.) b. Estimate the relative frequency of values less than 67. Choose the correct answer below. A. 0.17 B. 1.00 C. 0.52 D. 0.83 c. Estimate the relative frequency of values greater than 67. Choose the correct answer below. A. 1.00 B. 0.17 C. 0.83 D. 0.52 d. Estimate the relati
