an estimate (m) is used based upon a statistic such as the arithmetic or geometric mean of past returns. 3. Problems with estimates of the expected return To investigate the properties of the arithmetic mean and geometric mean of past returns as estimators of the discount rate, we assume that annual total return
Regular digital thermometers use electronic heat sensors to record body temperature. These thermometers can be used in the rectum, mouth or armpit. Armpit temperatures are usually the least accurate. Rectal temperatures provide the best readings for infants, especially those 3 months or younger, as well as children up to age 3. For older children and adults, oral readings are usually accurate â as long as the mouth is closed while the thermometer is in place.
Thus an oral temperature, measured with a thermometer placed under the tongue, is the most convenient and comfortable type of temperature measurement for adults. A normal oral temperature is 98.6Â°F or 37.0 Â°C. This is the accepted standard temperature for the normal body temperature.External measure of the bodyâs temperature such as axillary, tympanic membrane or skin temperatures are the least accurate and may take hours to reflect true changes in the bodyâs core temperature. r ectal temperatures is an internal measurement taken in the rectum, and is slightly higher at 99.6 Â°F or 37.6 Â°C. This is the best and most accurate measure of the bodyâs temperature. A rectal temperature can be taken on individuals of all ages, but it may be uncomfortable.
