10.51 Ground or Air? The earth's tempera W (which affects seed germination, crop survival in bad weather, and many other aspects of agricultural production) can be measured using either ground-based sensors or infrared-sensing devices mounted in aircraft or space satellites. Ground-based sensoring is tedious, requiring many replications to obtain an accurate estimate of ground temperature. On the other hand, airplane or satellite sensoring of infrared waves appears to introduce a bias in the temperature readings. To determine the bias, readings were obtained at five different locations using both ground- and air-based temperature sensors. The readings (in degrees Celsius) are listed here: th Location Ground Air 1 46.9 47.3 45.4 48.1 3 36.3 37.9 4 31.0 32.7 24.7 26.2 a. Do the data present sufficient evidence to indicate a bias in the air-based temperature readings? Explain. b.

How many paired observations are required to estimate the difference between mean temperatures

10.51 Ground or Air? The earth's temperature
(which affects seed germination, crop survival in bad
weather, and many other aspects of agricultural
production) can be measured using either ground-based
sensors or infrared-sensing devices mounted in aircraft
or space satellites. Ground-based sensoring is tedious,
requiring many replications to obtain an accurate
estimate of ground temperature. On the other hand,
airplane or satellite sensoring of infrared waves appears
to introduce a bias in the temperature readings. To
determine the bias, readings were obtained at five
different locations using both ground- and air-based
temperature sensors. The readings (in degrees Celsius)
