To begin to better understand personal experiences of headache pain, a drug manufacturer has asked 9 adults to ratetheir most recent headache on a scale of 0 to 100 (with 0 corresponding to no pain and 100 corresponding to the greatestpain the person has ever felt).

What are the two ways to understand the mean of a data set ? How would you go about giving examples to explain this to someone?
You work for an animal rescue organisation and you have recently found a female stray cat with 6 kittens. Because you are worried that the kittens may be underfed, you measure their weights (in grams). You collect the following data: 231, 185, 154, 182, 202, 220. Calculate the mean weight of these 6 kittens. (Provide your answer as a number rounded to the nearest integer.)
Suppose that a polling company surveyed 600 people about how much time they spend watching television each day. The results of this survey were compiled and used to create this relative frequency histogram. Assume that all percentages shown in the histogram are whole numbers. Each of the bars in this histogram includes only the left endpoint of the class except for the last bar, which also includes the right endpoint. What percentage of respondents said that they watch television at least six hours per day? How many respondents said that they watch television between three and five hours per day?
A psychologist has designed an index to measure the social perspectives of elementary school children. The index is based on ratings of a child’s responses to questions about a set of photographs showing different social situations. The following are the indices measured on a random sample of 16 children attending elementary school in a particular district. 48, 75, 69, 58, 60, 68, 59, 66, 71, 52, 49, 60, 54, 55, 70, 57 For the data the mean index is 60.69 and the standard deviation is 8.26. Perform a statistical test to determine if the population mean index is greater than 50. a) Name of hypothesis test: b) H0: c) HA: d) Test Statistic: e) Rejection region: f) Decision in the context of the problem:
The high temperatures for few cities are shown: 32,19,57,48,44,50,42,49,55,44. Calculate the Mean,Median, and the Mode of the data
Create and fill in a table with columns for (1) bin, (2) absolute frequency, and (3) relative frequency. Draw a histogram of the relative frequency distribution of Commuting Time in your sample. How would you characterize the shape of your histogram (e.g. uniform, symmetric, etc.)?
The sample data here is the cholesterol levels for 10 men diagnosed with high cholesterol. The first row represents levels from 10 men who did not use the drug and the second row from 10 different men who did use the drug. If we want to test the claim that the mean level for all men who use the drug is less than the mean for all men who do not use it, what is the appropriate alternative hypothesis? The mean cholesterol level of males who take the medicine is higher than the mean cholesterol levels of men who do not take it. There is a significant difference between males who use the medicine and men who do not use the drug in terms of mean cholesterol levels. The mean cholesterol level of males who take the medicine is lower than the mean cholesterol levels of men who do not take it. There is no significant difference between males who use the medicine and men who do not use the drug in terms of mean cholesterol levels.
Derrick is preparing to submit his taxes. Over the year, he kept track of certain deductions he is able to claim (all rounded to the nearest dollar). These values are given below. 65,144,97,144,103,98,101,127,58,151 He wants to create a histogram of the data using 4 classes. What values of Xscl, Xmin, and Xmax should he use?
Suppose we measure GPA for people in our class, we find the mean is 2.8 and the median is 3.2. What can you say is most likely true about GPAs in our class?
