The removal of the metabolic wastes of an organism is

A) Defecation
B) Renal artery
C) Respiration
D) Excretion

Box and Whisker Plot is also sometimes called:

A) Whisker Box
B) None of these
C) Box Whisker
D) Box Plot

AI Explanation

BIO401 Final Term AI Solved

Two or more events are said to be _________ , if the events do not have any outcomes in common.

A) mutually inclusive
B) none of these
C) interdependent
D) mutually exclusive

AI Explanation

Two or more events are mutually exclusive when they have no outcomes in common. Therefore, the occurrence of one event prevents the other from occurring simultaneously.

BIO401 Final Term AI Solved

Quantiles are more robust and less susceptible than _ if there are outlying observations in the data

A) Standard deviation
B) Mean
C) Dispersion
D) Mode

AI Explanation

Quantiles are robust measures that are less affected by extreme or outlying observations. The mean, by contrast, can be strongly influenced by unusually large or small values.

BIO401 Final Term AI Solved

In an array the Quartiles are _ cut-points that divides the values into 4 equal parts.

A) 3
B) 6
C) 4
D) 2

AI Explanation

Quartiles divide an ordered data set into four equal parts. Three cut-points, Q1, Q2, and Q3, are therefore required to create these four parts.

BIO401 Final Term AI Solved

Relative frequency in population is known as

A) None of these
B) Probability
C) Dispersion
D) Sampling

AI Explanation

Relative frequency represents the proportion of times an event occurs within a population. In probability theory, this relative frequency corresponds to the probability of the event.

BIO401 Final Term AI Solved

The location parameters which help us to determine the position of a particular observations in a data are called _______

A) Measures of observation
B) Measures of position
C) Measures of change
D) Local parameters

AI Explanation

Measures of position describe where a particular observation lies within a data set. Examples include quartiles, percentiles, and deciles.

If an Event consists of exactly one outcome, it is called

A) Simple complex event
B) Simple Event
C) None of these
D) Complex event

AI Explanation

A simple event consists of exactly one outcome from the sample space. An event containing two or more possible outcomes is called a compound or complex event.

BIO401 Final Term AI Solved

The positive square root of the variance is called _______

A) Standard deviation
B) Mode
C) Mean
D) Quartile

AI Explanation

__________________ is independent of the scale of measurement:

A) Dispersion
B) Coefficient of variation
C) Standard deviation
D) All

AI Explanation

The coefficient of variation is a relative measure of dispersion calculated as the standard deviation divided by the mean. Because it is a ratio, it is independent of the scale of measurement.

BIO401 Final Term AI Solved

Which one is not the condition for Binomial distributio?

A) For each trial, there are only two possible outcomes (success/failure).
B) There is a fixed number, n, of identical trials.
C) The probability of success, p, remains the same for each trial.
D) None

AI Explanation

All three listed statements are conditions of a binomial distribution: fixed identical trials, two possible outcomes per trial, and a constant probability of success. Therefore, none of the options A-C is an incorrect condition.
