question 245

Multiple Choice

At the beginning of 2017, a song sparrow population had 131 members.In the previous year, 21 birds were born and 32 birds died.Also in the previous year, 5 birds immigrated into the population and 9 birds emigrated from it.Which solution to the population growth equation, N_t = N₀ + (B - D) + (I - E) , is correct for this set of data?

• A) N_t = 131 + (21 - 5) + (32 - 9) N_t = 170
• B) N_t = 131 + (32 - 5) + (21 - 9) N_t = 170
• C) 131 = N₀ + (21 - 32) + (5 - 9) N₀ = 146
• D) N_t = 131 + (21 - 32) + (5 - 9) N_t = 116
• E) 131 = N₀ + (21 - 5) + (32 - 9) N₀ = 92

Definitions:

Null Hypothesis

A statement positing that there is no significant difference or relationship between specified populations, any observed difference being due to sampling or experimental error.

Probability

A measure of the likelihood that an event will occur, quantified between 0 and 1, where 0 indicates impossibility and 1 indicates certainty.

Null Hypothesis

A type of hypothesis used in statistics that suggests there is no significant difference or effect in a particular condition, serving as a default position until evidence suggests otherwise.

P < .05

A statistical threshold indicating that the probability of observing the obtained result, or more extreme, if the null hypothesis is true, is less than 5%.
