An amusement park keeps track of the percentage of individuals with season passes according to age category. An independent tourist company would like to show that this distribution of age category for individuals buying season passes is different from what the amusement park claims. The tourist company randomly sampled 200 individuals entering the park with a season pass and recorded the number of individuals within each age category. Age Category Child (under 13 years old) Teen (13 to 19 years old) Adult (20 to 55 years old) Senior (56 years old and over) Number of Individuals 56 86 44 14 The tourist company will use the data to test the amusement park’s claim, which is reflected in the following null hypothesis. H0:pchild=0.23H0:pchild=0.23, pteen=0.45pteen=0.45, padult=0.20padult=0.20, and psenior=0.12psenior=0.12. What inference procedure will the company use to investigate whether or not the distribution of age category for individuals with season passes is…
Each day a hospital records the number of people who come to the emergency room for treatment. In the last week, the observation from Sunday to Saturday are 11, 8, 12, 14, 7, 39, 57. Would you expect the Poisson distribution to better describe, or more poorly describe, the number of weekly admissions to the hospital for a rare disease? Why?
he Princeton Review, a company that tracks information about various colleges, reports that 30% of CofC students are out-of-state students. If we took many samples of CofC students, and for each sample calculate the proportion $\hat{p}$ of out-of-state students in that sample, what would be the center of this distribution?
Identify and sketch three distribution shapes that are symmetric.
Apply K-mean Clustering for the following single data set for two clusters (k=2). Data set = {2, 4, 9, 10, 3, 24, 38}
Each of the boxplots shown summarizes 24 student scores on a recent test in two different classes. The boxplots are drawn using a common numerical scale. Which of the following must be true? 1. The lower 25% of Class B are much more spread out than the lower 25% of Class A 2. More people scored below the lower quartile for Class A than Class B 3. The distribution for Class B is skewed left and has a noticeable outlier as well, while the distribution for Class A is somewhat skewed right 4.Class A had more people between the median and the lower quartile than Class B. 3.The distribution for Class A is somewhat symmetric, while the distribution for Class B is skewed right with a noticeable outlier as well
Consider the following two datasets: A = { 5 , 23 , 8 , 12 , 4 , 21 } and B = { 20 , 10 , 16 , 1 , 18 , 8 , 4 } . select all correct options The sample medians of the datasets are equal. The sample means of the datasets are not equal The sample means of the datasets are equal. The ranges of the datasets are equal. The sample medians of the datasets are not equal.

Consider the population of car drivers in the United States, and how many traffic tickets they've each received over the course of their lives. Would the distribution of these traffic tickets be left-skewed (where we often see mean median)? Pick ONE option Left-skewed Right-skewed It would be unreasonable to guess Potentially both at once
when a population distribution is symmetric, unimodal, without outliers?
3. We want to compare initial salaries of graduates with Marketing major and graduates with Finance Major. We compare the salaries of these two groups with the same GPA. Example, salary of marketing graduate with GPA 3.5 is compare with the salary of Finance graduate with the same GPA 3.5. Assume salaries are normally distributed for both groups with unequal variances. We want to study the mean of the difference of these two groups. This is a a) t-test with equal variances b) t-test with unequal variances c) t-test for paired data.
