A gambler complained about the dice. They seemed to be loaded! The dice were taken off the table and tested one at a time. Onedie was rolled 300 times and the following frequencies were recorded.Outcome123456Observed644562324750frequency OA USE SALTDo these data indicate that the die is unbalanced?

Choose the correct definition of a random variable from the list below. A random variable is one whose values correspond to a scale with a countable number of values. one that occurs in one of two possible states, labeled success and failure. one that is measured to explain changes in the response variable. one whose values describe the outcome of some chance process. O one whose effect in an experiment cannot be distinguished from the effects of other variables.
1. What is a random variable? Give an example. Suppose you are shopping online for a new toy for your dog. As you look at the product reviews, you see the following distribution of ratings. Use this table for questions 2-5. Stars Frequency 6. 4 3 3 1 1 2. Sketch a data visualization of the distribution of stars. 3. What is the probability that a randomly chosen reviewer gave the dog toy 3 stars? What is the probability that a randomly chosen reviewer gave the dog toy 3 or fewer stars?

I need help. How do I find the two missing expected values when two of the expected values are already given? Suppose you are reading a study conducted in the year 2000 about adolescent girls with anorexia nervosa in the United States. The authors report the following frequency data on regions where the 522 adolescent girls with anorexia nervosa in their random sample reside: Observed Frequencies Region West South Midwest Northeast 110 206 110 96 You wonder whether the differences in the frequencies are due to the disease being more prevalent in certain areas of the country, whether the study simply included more girls from certain regions, or whether the distribution matches the geographic distribution of the US population. You obtain the following data from the 2000 census: Percent Distribution of the US Population by Region Region West South Midwest Northeast 22.46% 35.62% 22.88% 19.04% [Source: Hobbs F., & Stoops, N.
