Answer:
a

b

Step-by-step explanation:
From the question we are told that
The population proportion is
Considering question a
The sample size is 
Generally the standard deviation of this sampling distribution is
=>
=>
The sample proportion of cans that are recycled is

=> 
Generally the probability that 300 or more will be recycled is mathematically represented as


From the z table the area under the normal curve to the left corresponding to 1.591 is

=> 
Considering question b
Generally the lower limit of sample proportion of cans that are recycled is

=> 
Generally the upper limit of sample proportion of cans that are recycled is

=> 
Generally probability that between 260 and 300 will be recycled is mathematically represented as

=> 
=> 
From the z table the area under the normal curve to the left corresponding to 1.136 and -3.55 is

and

So

=>
