Which of the following is true? O O Parameters estimate statistics statistics estimate parameters Parameters are characteristics of samples and statistics are characteristics of populations

For the data set (−2,−3),(1,1),(5,6),(9,6),(12,11), find interval estimates (at a 92.2% significance level) for single values and for the mean value of y corresponding to x=4 Note: For each part below, your answer should use interval notation. Interval Estimate for Single Value =  Interval Estimate for Mean Value =

Percent Obese by StateComputer output giving descriptive statistics for the percent of the population that is obese for each of the 50 US states, from the USStates dataset, is given in the table shown below. Since all 50 US states are included, this is a population, not a sample. Descriptive Statistics: Obese Variable N   Mean SE Mean StDev Minimum   Median   Maximum Obese 50 0 28.766 0.476 3.369 21.300 26.375 29.400 31.150 35.100 Percent of the population that is obese by state Click here for the dataset associated with this question.   (a) What are the mean and the standard deviation Enter your answer in accordance to item (a) of the question statement % Enter your answer in accordance to item (a) of the question statement %(b) Calculate the z-score for the largest value and interpret it in terms of standard deviations.

Can I have an explanation of how to do this I can’t seem to understand it I keep getting it wrong

||| O DATA ANALYSIS AND STATISTICS Choosing the best measure to describe data Answer the questions below. (a) The 9 members of a fraternity have the following test scores: 118, 119, 121, 124, 125, 127, 129, 130, 182. Which measure should be used to summarize the data? Mean Median Mode (b) In Prof. Allen's class, the 10 students had the following scores on the last midterm: 128, 130, 131, 132, 135, 136, 141, 142, 143, 144. Which measure should be used to summarize the data? Mean Median Mode (c) Each member of the football team was asked to report the year he was born. Which measure gives the most common year of birth? Mean Median Mode X Ś

Using inferential statistics, the goal is usually to generalize from a to a population; sample DV; IV data; variable sample; population

Question attached    Bottom question asks Is the mode a useful measure of center for this data set? Yes or no.
