. Computers in some vehicles calculate various quantities related to performance. One of these is fuel efficiency, or gas mileage, usually expresses as miles per gallon (mpg). For one vehicle equipped in this way, the miles per gallon were recorded each time the gas tank filled, and the computer was then reset. Here are the mpg values for a random sample of 20 of these records:

41.5

50.7

36.6

37.3

34.2

45.0

48.0

43.2

47.7

42.2

43.2

44.6

48.4

46.4

46.8

39.9

37.3

43.5

44.3

43.3

Find a 95% confidence interval for μ, the mean miles per gallon for this vehicle.

Computers in some vehicles calculate various quantities related to performance. One of these is the fuel efficiency, or gas mileage, usually expressed as miles per gallon (mpg). A particular vehicle equipped in this way is advertised as having a fuel efficiency of 41 mpg. A woman who owns one of these vehicles believes she is getting even higher fuel efficiency, so she recorded the mpg each time the gas tank was filled, and then reset the computer. For 18 recordings,...

A gardener plants 300 sunflower seeds (of a brand called KwikGrow) and, after 2 weeks, measures the seedlings’ heights (in mm). These heights are recorded in the file Sunflower.csv. He is interested in testing whether the mean height of sunflowers grown from KwikGrow seeds is greater than 33 mm two weeks after planting. He decides to conduct a hypothesis test by assuming that the sampling distribution of the sample mean has a normal distribution. For the purposes of this question,...
