Explanation Given info: To compare the tastiness and juiciness of the tomatoes, six tomato plants are considered and each of the plants is randomly assigned with the three amounts of new fertilizer. That is, some plants are given none of the amounts of new fertilizer, half the amount of recommended fertilizers, and the full amount of recommended fertilizer. Justification: The answers may varyand one of the possible answers is given below: Confounding : In a study, confounding occurs when the apparent relationship between an explanatory variable and a response variable is due to some other variablesthatmay not be accounted for in that study. In other words, one can say that confounding in a study occurs when the effects of two or more explanatory variables are not separately identified. Confounding usually occurs due to a different variable that has not been accounted for in the experiment. Confounding variable: A confounding variable is measured and considered in a study but its effect cannot be distinguished from a second explanatory variable in that study...

Addition Rule of Probability

It simply refers to the likelihood of an event taking place whenever the occurrence of an event is uncertain. The probability of a single event can be calculated by dividing the number of successful trials of that event by the total number of trials.

Expected Value

When a large number of trials are performed for any random variable ‘X’, the predicted result is most likely the mean of all the outcomes for the random variable and it is known as expected value also known as expectation. The expected value, also known …

Probability Distributions

Understanding probability is necessary to know the probability distributions. In statistics, probability is how the uncertainty of an event is measured. This event can be anything. The most common examples include tossing a coin, rolling a die, or choosi…

Basic Probability

The simple definition of probability it is a chance of the occurrence of an event. It is defined in numerical form and the probability value is between 0 to 1. The probability value 0 indicates that there is no chance of that event occurring and the prob…
