Answer:
The probability that the sample proportion is between 0.35 and 0.5 is 0.7895
Step-by-step explanation:
To calculate the probability that the sample proportion is between 0.35 and 0.5 we need to know the z-scores of the sample proportions 0.35 and 0.5. 
z-score of the sample proportion is calculated as 
z= where
 where 
- p(s) is the sample proportion of first time customers 
- p is the proportion of first time customers based on historical data
For the sample proportion 0.35:
z(0.35)= ≈ -1.035
 ≈ -1.035
For the sample proportion 0.5:
z(0.5)= ≈ 1.553
 ≈ 1.553
The probabilities for z of being smaller than these z-scores are:
P(z<z(0.35))= 0.1503 
 P(z<z(0.5))= 0.9398
Then the probability that the sample proportion is between 0.35 and 0.5 is 
P(z(0.35)<z<z(0.5))= 0.9398 - 0.1503 =0.7895
 
        
             
        
        
        
1 + 0.09 = 1.09
90 * 1.09 = 98.1
The original price of the in-line skates was $98.1
