30 Fuel efficiency. 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). For one vehicle equipped in this way, the miles per gallon were recorded each time the gas tank was filled, and the computer was then reset. Here are the mpg values for a random sample of 20 of these records: MPG 41.5 43.2 50.7 44.6 36.6 48.4 37.3 46.4 34.2...
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). For one vehicle equipped in this way, the miles per gallon were recorded each time the gas tank was filled, and the computer was then reset. In addition to the computer's calculations of miles per gallon, the driver also recorded the miles per gallon by dividing the miles driven by the number of...

Computers in some vehicles calculate various quantities related to performance. One of these is the fuel efficiency. For one vehicle equipped in this way, the number of ‘liters per 100 kilometers’ driven were recorded each time the gas tank was filled, and the computer was then reset. Below are the ‘liters per 100 kilometers’ driven for a random sample of 20 of these records. 5.7, 4.6, 6.4, 6.3, 6.9, 5.2, 4.9, 5.4, 4.9, 5.6, 5.4, 5.3, 4.9, 5.1, 5.0, 6.0,...
Name Practice 4. Quiz 4 For the problems below, determine if data collection is Matched Pairs or Independent Samples 1 The design of controls and instruments has a large effect on how easily people can use them. A student project investigated this effect by asking 25 right-handed students to turn a knob (with their right hands) that moved an indicator by screw action. There were two identical instruments, one with a right-hand thread (the knob turns dockwise) and the other...

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 below. 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, you may assume...
My Ask You C-reactive protein (CRP) is a substance that can be measured in the blood. Values increase substantially within & hours of an infection and reach a peak within 24 to 48 hours after. In adults, chronically high values have been linked to an increased risk of cardiovascular disease. In a study of apparently healthy children aged 6 to 60 months in Papua New Guinea, CRP was measured in 90 children. The units are milligrams per liter (mg/l). Here...
