1 answer:
Answer:
56 students scored in the range of 1301 to 1600.
Step-by-step explanation:
The given question is without any figure or attachment. Here is the figure attached with the answer.
In the figure attached,
total number of students who took SAT = 400
Percentage of the students who scored 1301 to 1600 range = 14% (given in the pie chart)
Total number of students who are in this range = 14% of total number of students
=
= 56

Answer:
101, 3, 0.025, 0.7416
Step-by-step explanation:
Given that a random sample of n = 16 observations is selected from a population that is normally distributed with mean equal to 101 and standard deviation equal to 12.
As per central limit theorem we have
a) Mean of sample mean =
Std deviation of sample mean =
Mean = 101
Std dev =3.00
b)
c) the probability that the sample mean deviates from the population mean μ = 101 by no more than 4.
