Answer: 0.05
Step-by-step explanation:
- Sampling error is the error occurs by considering sample for study instead of entire population.
Given : The proportion of items in a population that possess a specific attribute is known to be 0.45.
Sample size : n= 100
Sample proportion of items in a population that possess a specific attribute : 
Now, the formula to find the sampling error :



Hence, the sampling error =0.05
A.)y=1.25x+12.5
B.)ridecost+admission=total
if x=number of tickets and y is total and cost per ride is 1.25,
1.25x+admission=y
when we solve
when x=25, y=43.75
