Answer #1

Consider a sample with
a mean of 60 and a standard deviation of 6. Use Chebyshev's theorem
to determine the percentage of the data within each of the
following ranges (to the nearest whole number).
50 to 70, at least
%
45 to 75, at least
%
52 to 68, at least
%
47 to 73, at least
%
44 to 76, at least %

Consider a sample with
a mean of 60 and a standard deviation of 4. Use Chebyshev's theorem
to determine the percentage of the data within each of the
following ranges (to the nearest whole number).
40 to 80, at least %
45 to 75, at least %
52 to 68, at least %
47 to 73, at least %
44 to 76, at least %

Consider a sample with a mean of 40 and a standard deviation of
4. Use Chebyshev's theorem to determine the percentage of the data
within each of the following ranges (to the nearest whole
number).
20 to 60, at least %
15 to 65, at least %
32 to 48, at least %
27 to 53, at least %
22 to 58, at least %

Consider a sample with a mean of 30 and a standard deviation of
6. Use Chebyshev's theorem to determine the percentage of the data
within each of the following ranges(to the nearest whole
number).
a) 10 to 50, at least ____%
b)15 to 45, at least ___%
c) 22 to 38, at least ___%
d) 17 to 43, at least ___%
e) 14 to 46, at least ___%

A major cab company in Chicago has computed its mean fare from
O'Hare Airport to the Drake Hotel to be $29.98 , with a standard
deviation of $4.08. Based on this information, complete the
following statements about the distribution of the company's fares
from O'Hare Airport to the Drake Hotel. (
a) According to Chebyshev's theorem, at least 36% of the fares
lie between ____ and ____ . (Round your answer to 2 decimal
places.)
(b) According to Chebyshev's theorem,...

In a certain distribution, the mean is 100 with a standard
deviation of 4. Use Chebyshev's Theorem to tell the probability
that a number lies between 92 and 108
The probability a number lies between
92
and
108
is at least

A sample mean, sample size, population standard deviation,
and confidence level are provided. Use this information to complete
parts (a) through (c) below.
x=32 n=22 0=3 confidence level= 90%

A set of data is normally distributed with a mean of 44 and a
standard deviation of 3.2. Which of the following statements are
NOT true? [Please make sure to explain why]
I. 68% of the values are between 37.6 and 50.4.
II. 13.5% is between 37.6 and 40.8.
III. 5% of the values are lower than 37.6 or higher than
50.4

A probability distribution has a mean of 50 and a standard
deviation of 10. Use Chebyshev's inequality to find the minimum
probability that an outcome is between 10 and 90. (Round your
answer to four decimal places.)

A probability distribution has a mean of 70 and a standard
deviation of 2. Use Chebyshev's inequality to find the minimum
probability that an outcome is between 65 and 75. (Round your
answer to four decimal places.)
