Expert Solution
Solution
Given that,
population proportion = p = 0.60
1 - p = 1 - 0.60 = 0.40
n = 500
= p = 0.60
= 
P(
0.610 ) = 1 - P(
0.610 )
= 1 - P((
-
) /
( 0.610 - 0.60
) / 0.0219 )
= 1 - P(z 0.46 )
Using z table
= 1 - 0.6772
= 0.3228

PYTHON
You need to control the number of people who can be in an
oyster bar at the same time. Groups of people can always leave the
bar, but a group cannot enter the bar if they would make the number
of people in the bar exceed the maximum of 100 occupants. Write a
program that reads the sizes of the groups that arrive or depart.
Use negative numbers for departures. After each input, display the
current number of occupants....
