The accompanying data represent the miles per gallon of a random sample of cars with a three-cylinder, 1.0 liter engine.
31.5 36.0 37.8 38.5 40.1 42.234.2 36.2 38.1 38.7 40.6 42.534.7 37.3 38.2 39.5 41.4 43.435.6 37.6 38.4 39.6 41.7 49.3
(a) compute the z-score corresponding to the individual who obtained 32.3 miles per gallon. interpret this result. (b) determine the quartiles. (c) compute and interpret the interquartile range, iqr. (d) determine the lower and upper fences. are there any outliers?

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it

during a tunnel construction project, engineers used explosives to excavate partway into a mountain. but due to constraints and environmental concerns, they later introduced a tunnel boring machine (tbm) to excavate the rest of the tunnel. the length and of the completed tunnel (in feet) is based on the number of days since the tbm started working. the length can be calculated using the equation y = 25x + 225. what does the y-intercept represent in this scenario?
