The accompanying data below represent the miles per gallon of a random sample of cars with a​ three-cylinder, 1.0 liter engine. 32.7 35.7 38.0 38.7 40.2 42.1 34.1 36.4 38.1 39.1 40.6 42.9 34.5 37.4 38.3 39.5 41.4 43.4 35.6 37.7 38.6 39.6 41.6 48.9 Compute the​ z-score corresponding to the individual who obtained 37.4 miles per gallon. Interpret this result. The​ z-score corresponding to the individual is ____ and indicates that the data value is _____ standard​ deviation(s) above/below the mean/median (Type integers or decimals rounded to two decimal places as​ needed.)

Referring to Table 2, the mean square for the factor filling time is____ 1). 0.9030 2). 0.4234 3). 0.4515 4). 0.2117
