Answer: option E - It may have blinded your study.

Explanation:

A confounder is a factor, in data analysis, that causes the effects of two distinct processes to be indistinguishable/ unknown.

Of course, the confounder (factor) could have made the protective effect against heart disease a function of more than just physical activity - bringing other factors like heredity or diet history etc into consideration.

So, the confounder (factor) may have blinded your study.

Plz help due now As children age, how do their psychological and physical abilities change?
ArbitrLikvidat [17]

Answer:

The various stages of development in children are reached at a unique time and rate for every child. But there are a number of common key categories to consider when looking at your child’s early health and development. Explanation:

In infancy, toddlerhood, and early childhood, the body’s physical development is rapid (Figure 1). On average, newborns weigh between 5 and 10 pounds, and a newborn’s weight typically doubles in six months and triples in one year. By 2 years old the weight will have quadrupled, so we can expect that a 2 year old should weigh between 20 and 40 pounds.

HOPE THIS HELPS :)
