Answer:
A. 64/125
B. 124/125.
Step-by-step explanation:
A). As the events ( germinate or not germinate) are independent we multiply the probabilities.
Prob(All seeds germinate) = 4/5*4/5*4/5 = 64/125.
B). Probability of at least one germinating = 1 - probability that none germinate
Probability of 1 seed not germinating = 1 -45 = 1/5.
So Prob(at least one germinating)
= 1 - (1/5 * 1/5 * 1/5)
= 1 - 1/125
= 124/125.

Answer:
Population: Adults in the United States
Sample: 2276 adults in the United States
33% is a statistic.
Step-by-step explanation:
The population consists of adults in the United States because that is the wider range, and the sample is 2276 of those adults.
The value 33% is an statistic due to the definitions of both words. A statistic is defined as a fact or piece of data obtained from a study of a large quantity of numerical data. While a parameter is a numerical or other measurable factor forming one of a set that defines a system or sets the conditions of its operation.
This seems like it would be more of a bar graph. The way to construct this would be to make x (bottom) the test scores and y (left) the amount of students who got that score. You would be able to conclude that a majority of students in the class got between 80 and 89.
