Unoccupied seats at the Cardinal’s football stadium causes the football team to lose revenue. The Cardinal’s owner wants to estimate the mean number of unoccupied seats per game over the past few years. To accomplish this, the records of 225 games are randomly selected and the number of unoccupied seats is noted for each of the sampled games. The sample mean is 11.6 seats and the sample standard deviation is 4.1 seats. x-=
Solutions
Expert Solution
n = Sample Size = 225
= Sample
mean = 11.6
s = Sample SD = 4.1
SE = s/
= 4.1/
=
0.2733
Take 
= 0.05
ndf = 225 - 1= 224
From Table,critical values of t = 
1.9706
Confidence Interval:
11.6 (1.9706 X
0.2733)
= 11.6 0.5386
= ( 11.0614, 12.1386)
So,
Answer is:
( 11.0614, 12.1386)

Unoccupied seats at the Cardinal’s football stadium causes the
football team to lose revenue. The Cardinal’s owner wants to
estimate the mean number of unoccupied seats per game over the past
few years. To accomplish this, the records of 225 games are
randomly selected and the number of unoccupied seats is noted for
each of the sampled games. The sample mean is 11.6 seats and the
sample standard deviation is 4.1 seats. n – 1 =

Unoccupied seats on flights cause airlines to lose revenue.
Suppose a large airline wants to determine of the mean number of
unoccupied seats on all its flights is greater than 10. To
accomplish this, the records of 60 flights are randomly selected
and the number of unoccupied seats is noted for each of the sampled
flights. The sample mean is 11.4 seats and the sample standard
deviation is 3.4 seats. Test the claim that mean number of
unoccupied seats on...

Unoccupied seats on flights cause airlines to lose revenue.
Suppose a large airline wants to estimate its average number of
unoccupied seats per flight over the past year. Two hundred and
twenty-five flight records are randomly selected and the number of
unoccupied seats is noted, with a sample mean of 11.6 seats and a
population standard deviation of 4.1 seats. How many flights should
we select if we wish to estimate μ to within 5 seats and
be 95 percent...

A stadium designer has placed 900 seats in one section of the
stadium. Assume that the weights of people who will occupy those
seats are i.i.d. with a mean of 160 pounds and an SD of 25 pounds.
Fill in the blanks with numbers and show your calculation: With
chance about 99%, the total weight of people in the 900 seats will
be in the range ⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯± ⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯

In Python
There are three seating categories at a stadium. Class A seats
cost $20, Class B seats cost $15, and Class C seats cost $10. Write
a program that asks how many tickets for each class of seats were
sold, then display the amount of income generated from ticket
sales. \
your program MUST contain a main
function, a calcIncome function, and a
showIncome function.
Your main function should get the number of
seats sold for each category. The...
