A store owner asks each person to write “Yes” or “No” on a slip of paper as they leave, secretly writing down whether they were happy with their experience. At the end of the day, the owner selects 12 slips at random and looks at them. These were the results:
yes, yes, yes, no, yes, no, yes, yes, no, yes, no, yes

a. Estimate the proportion of all shoppers who were happy with their experience that day.

2/3

Step-by-step explanation:

Probability=number of favourable outcomes/number of possible outcomes

P(customers who were happy with their experience)= 8/12 = 2/3

two-third of total customers (12 people) were happy with their experiences.

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.
