A gambler complained about the dice. They seemed to be loaded! The dice were taken off the table and tested one at a time. One die was rolled 300 times and the following frequencies were recorded.5OutcomeObservedfrequency O3 459 32 44 56USE SALT164245Do these data indicate that the die is unbalanced? Use a 1% level of significance.

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.
An experiment consists of rolling a pair of dice once. Let Y be the random variable representing the absolute value of the differece of the numbers that come up.
A new store is deciding what pens to stock up on. The owner wants to know if each colour of pen is equally popular so they can start ordering supplies. To find out, the owner selects a random sample of 100 students and asks them "What colour of pen do you prefer: Blue, Black, Red, or Green?" Here is the data collected from the sample of students: Blue = 35 people Black 31 people Red = 21 people Green 13 people = Calculate the appropriate test statistic for these data to determine if there is a preference in pen colour. Enter your calculated statistic below Answer:

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.
