The irradiation of food to destroy bacteria is a growing phenomenon. In order to determine which one of two methods of irradiation is best, a scientist took a random sample of 100 one- pound packages of minced meat and subjected 50 of them to irradiation method 1 and the remaining 50 to irradiation method 2. The bacteria count was measured and the following statistics were computed. Method 1 X₁ = 86 s² = 324 Method 2 X₂ =98 2 s₂ = 841 The scientist noted that the data are normally distributed.

The irradiation of food to destroy bacteria is a growing phenomenon. In order to determine
which one of two methods of irradiation is best, a scientist took a random sample of 100 one-
pound packages of minced meat and subjected 50 of them to irradiation method 1 and the
remaining 50 to irradiation method 2. The bacteria count was measured and the following
statistics were computed.
Method 1
X₁ = 86
= 324
Method 2
X₂ =98
s² = 841
The scientist noted that the data are normally distributed.
