Chapter PIII, Problem 13RE

To determine

To find: that it is an observational study, sample survey or an experiment and all the parameter of this study and survey and types of conclusions could be reached on the basis of given data.

Explanation of Solution

Researchers have gene therapy data. This was an experiment and it is not suitable for any design.

The experiment had one gene therapy factor and 2 levels of gene therapy and no gene therapy, resulting in 2 treatments.

The function of randomization is that the treatment group does not have any knowledge about random allocation. The response factors are the quantity of food eaten and weight lost.

The experiment concludes that the responsibility for stabilising heart muscle in the laboratory test is gene therapy.
