Answer:
C
Step-by-step explanation:
In this question, we are asked to select which of the options best answer the question.
We proceed as follows;
Using the information given,
Each of the 110 students in a statistics class selects a random sample of 35 Quiz scores
from a population of 5000 scores. They are not given the population mean and standard deviation.
Now, using these data, each student then construct a 90% confidence interval for µ which is the average Quiz score in the population of 5000 students.
By definition, the population mean values will definitely be within the limits of this
confidence interval.
Thus, the correct answer is, Option (c)
Answer:
210
Step-by-step explanation:
In a normal distribtuion mean=mode=median
so 210=median
5 1/4 m = 5.25m
50 cm = 0.5 m
So 5 1/4 m - 50 cm = 5.25 - 0.5 = 4.75 m
Let
where we assume |r| < 1. Multiplying on both sides by r gives
and subtracting this from 
gives
As n → ∞, the exponential term will converge to 0, and the partial sums will converge to
Now, we're given
We must have |r| < 1 since both sums converge, so
Solving for r by substitution, we have
Recalling the difference of squares identity, we have
We've already confirmed r ≠ 1, so we can simplify this to
It follows that
and so the sum we want is
which doesn't appear to be either of the given answer choices. Are you sure there isn't a typo somewhere?
