Consider the following two sample data sets.Set 1:1021132618 DSet 2:3.8a. Calculate the coefficient of variation for each data set.b. Which data set has less consistency (or more variability)?a. The coefficient of variation for data set 1 is %.(Round to one decimal place as needed.)The coefficient of variation for data set 2 is %.(Round to one decimal place as needed.)b. Which data set has less consistency (or more variability)? Choose the correct answer below.O A. Data set 1 has less consistency (or more variability) because its coefficient of variation is greater.O B. Data set 2 has less consistency (or more variability) because its coefficient of variation is greater.O C. Data set 1 has less consistency (or more variability) because its coefficient of variation is less.O D. Data set 2 has less consistency (or more variability) because its coefficient of variation is less.592tv

A social media app is conducting a study on the amount of time users spend on the app. They collect the following variables. Age Years: How old they are in years? Income: Monthly Income Location: What country do they live in? Device: Do they use an iPhone, Samsung, other? Service: Who provides their mobile phone service? For example: T-Mobile, At&t, Verizon, ect Hours: How many hours do they spend on the app per week. A) Which variable could the research construct a one proportion z-interval for? B) The social media app just launched a new algorithm that suggest content in an effort to increase the amount of time the user spends on the app. The researchers want to use the survey results to see if there is statistically significant evidence that on average users spend more than 10 hours per week on the social media app. The researchers found in their sample of 44 users, the mean hours spent on the app is 10.5 hours with a standard deviation of 5.675 hours.

For the variables time spent on homework and exam grade, which is more naturally the response variable and which is the explanatory variable? O Time spent on homework: response variable Exam grade: explanatory variable O Time spent on homework: explanatory variable Exam grade: response variable
Some research situations are summarized below. For each situation, identify all variables.Then, for each variable, note the level of measurement AND whether it is an independent or dependent variable. a.Ahealth researcher is interested in studying patient compliance (whether or not patients take the medicine their doctor prescribes). She surveys 800 diabetic patients, and finds compliance to be linked to patient age, education, gender, and socioeconomic status. b. A market researcher is hired by Target to see how customers buying habits have changed before and after COVID. The researcher studies how much each customer spent (in $s), how frequently they visited the website each month, how frequently they visited the store each month. They report that, since March, customers are spending less, visiting the website more frequently, and shopping in person less frequently.
