1. an ecologist studying starfish populations collects the following data on randomly-selected 1-meter by 1-meter plots on a rocky coastline. --the number of starfish in the plot. --the total weight of starfish in the plot. --the percentage of area in the plot that is covered by barnacles (a popular food for starfish). --whether or not the plot is underwater midway between high and low tide. how many of these measurements can be treated as continuous random variables and how many as discrete random variables? a) three continuous, one discrete. b) two continuous, two discrete. c) one continuous, three discrete. d) two continuous, one discrete, and a fourth that cannot be treated as a random variable. e) one continuous, two discrete, and a fourth that cannot be treated as a random variable.

Respuesta :

2 measurements can be treated as continuous random variables. 1 discrete random variable, and a fourth that cannot be treated as a random variable. (option d)

There are a few ways that a continuous random variable differs from a discrete variable: Due to the fact that it can contain an infinite number of values within a given interval, continuous random variables are typically uncountable. Measurements like height, weight, distance, and a plethora of other decimal values are examples of these variables. On the other hand, discrete random variables have values that can be counted, and the values of successive values are typically whole numbers.

In the above scenario, The number of starfish is a discrete variable, whereas the starfish's weight and percentage of the plot's area are continuous variables.

It is not a random variable whether the plot is in progress or halfway between high tide and low tide.
