The manager of a department store wants to know if any of the company's 281 employees would buy a reduced gym membership. The manager surveyed 70 randomly chosen employees, and 50 reported they would buy a reduced gym membership.

201 employees

Step-by-step explanation:

Question wants to know the predicted number of employees from the total number that would buy a reduced gym membership.

Going by the number of employees from the sample of 70 that said they would prefer a reduced membership, one can estimate a predicted value for the number of employees from the total population of 281 that would want the same.

Find the percentage that would want a reduced membership from the sample:

= 50 / 70 * 100%

= 71.43%

Apply this to the total population:

= 71.43% * 281

= 200.7

= 201 employees

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
