Question

An exerment was conducted to observe the effect of anincrease in temperature on the potency of an antbiotic. Three1-ounce portions of the antbiotic were stored for equal lenghts oftime at each of the following Fahrenheit temeratures : 30 degree,50 degree , 70 degree, and 90 degree. The potency readings observedat the expermential period were as shown in the followingtable. potency readings(y)    38, 48,29           32,26, 33          19, 27 ,23            14, 19, 21 Temperature(x)           30degree          50degree            70degree              90 degree Find the least-squares line appropriate for this data An exerment was conducted to observe the effect of anincrease in temperature on the potency of an antbiotic.

Explanation / Answer

Using Minitab, for the given data the appropriate least -squares line is,

Potency Readings = 47.917- 0.3417 Temparature
