Step-by-step explanation:
Hello!
The population is the set of elements that you are interested in studying. In this example, the instructor wants to know the number of days Lake Tahoe Community College math students are absent from class during a quarter. To do so she will take a random sample of math students and register the number of absences of each student. Each math student is an element of the population.
Then the population is "Lake Tahoe Community College math students"
I hope it helps!
Answer:
Step-by-step explanation:
Given that the time to complete a standardized exam is approximately normal with a mean of 70 minutes and a standard deviation of 10 minutes.
P(completing exam before 1 hour)
= P(less than an hour) = P(X<60)
=P(Z<
)
=0.5-0.34=0.16
i.e. 16% of students completed the standardized exam.
If it’s blank and just a negative sign the answer should be -1
Answer:
32$ < x < 48$
Step-by-step explanation:
Erika estimates that her destination is between 200 and 300 miles away.
When we divide 200 with 25 miles we get 200/25 = 8 gallons
When we divide 300 with 25 miles we get 300/25 = 12 gallons
When we multiply 8 · 4 = 32$ we get amount of money for destination
200 miles x = 32$
When we multiply 12 · 4 = 48$ we get amount of money for destination
300 miles x = 32$
Since that the estimate destination is between 200 miles and 300 miles
then the best estimate for the amount of money is between
32$ < x < 48$
