| 21-34. What's the design? Read each brief report of statistical research, and identify a) whether it was an observational study or an experiment. If it was an observational study, identify (if possible) b) whether it was retrospective or prospective. c) the subjects studied and how they were selected. d) the parameter of interest. e) the nature and scope of the conclusion the study can reach. If it was an experiment, identify (if possible) b) the subjects studied. c) the factor(s) in the experiment and the number of levels for each. d) the number of treatments. e) the response variable measured. f) the design (completely randomized, blocked, or matched). g) whether it was blind (or double-blind). h) the nature and scope of the conclusion the experiment can reach.

Use the given minimum and maximum data entries, and the number of classes, to find the class width, the lower class limits, and the upper class limits. minimum = 20, maximum = 135, 8 classes .... . The class width is (Type a whole number.)
Suppose we have a dataset containing 50 rows, one row for each state. The population of each state, measuredin millions of people, is a variable in that data set. Below is a histogram for the population data. I have attached the bar graph- I am havinng trouble discerning which axis is the state and which axid is the population count? theres only 14 on one axis and 44 on the other. Doesn't make sense for a state to have a zero population. Can you tell which is which? a) What proportion of states have a population between 6 and 10 million? what is the mean population? what is the median population?

We discuss how to test for an association between two categorical variables in Section 6.8. A marine research team records the number of fish from 3 species that they find at different depth categories in the ocean. They are interested in assessing whether or not there is a relationship between the depth category (close to surface, mid-level, ocean floor) and the fish species found (species A, species B, species C). A two-way table showing the classification of a sample of 150 observations is given below. If the variables for the ocean depth category and the species are independent, how would you calculate the expected number of fish that are at the mid-level and from species C? Expected number =
Plz answer without plagiarism .is this correct?.
A particular country has 40 total states. If the areas of all 40 states are added and the sum is divided by 40, the result is 193,549 square kilometers. Determine whether this result is a statistic or a parameter. Choose the correct answer below. O A. The result is a statistic because it describes some characteristic of a population. O B. The result is a parameter because it describes some characteristic of a sample. O C. The result is a parameter because it describes some characteristic of a population. O D. The result is a statistic because it describes some characteristic of a sample.
