The simple linear regression model is yiequalsbeta0plusbeta1xiplusepsilon i. for what does yi stand? choose the correct answer below. a. it is the slope of the population regression line. b. it is the residual of the ith observation in the population. c. it is the observed value of the response variable for the ith observation in the population. d. it is the value of the explanatory variable for the ith observation in the population. e. it is the y-intercept of the population regression line.

every 5 customers that walk in, only 2 buy popcorn.

step-by-step explanation:

basically 2/5.

brainliest would be appreciated.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
