A manufacturer of “Keep it Warm” bags is interested in comparing the heat retention of bags when used at five different temperatures (100 oF, 125 oF, 150 oF, 175 oF, and 200 oF). Thirty bags are selected randomly from last week’s production and randomly assigned, six each, to five different groups. Items from group 1 at beginning temperature 100 oF were kept in bags for an hour, and the temperatures of those items were recorded after an hour. Similarly, groups 2 to 5 were assigned items at 125 oF, 150 oF, 175 oF, and 200 oF, respectively. a. Identify the type of study used here. b. What type of inference is possible from this study?

Question
A manufacturer of “Keep it Warm” bags is interested in comparing the heat retention of bags
when used at five different temperatures (100 oF, 125 oF, 150 oF, 175 oF, and 200 oF). Thirty bags
are selected randomly from last week’s production and randomly assigned, six each, to five
different groups. Items from group 1 at beginning temperature 100 oF were kept in bags for an
hour, and the temperatures of those items were recorded after an hour. Similarly, groups 2 to 5
were assigned items at 125 oF, 150 oF, 175 oF, and 200 oF, respectively.
a. Identify the type of study used here.
