Answer:  12
Step-by-step explanation:
The formula to find the sample size is given by:-
 , where
 , where  is the population standard deviation,
 is the population standard deviation,  is the z-value for the
 is the z-value for the  confidence interval and E is the margin of error .
 confidence interval and E is the margin of error .
As per given , we have
Population standard deviation : 
z-value for 95% confidence interval : 
Margin of error : E= 3
Then, the required minimum sample :-

Hence, the required minimum sample size = 12
 
        
             
        
        
        
Answer:
a) 0.033
b) 0.468
c) 100 
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 105.3
Standard Deviation, σ = 8
The amount x of miraculin produced (measured in micro-grams per gram of fresh weight) had a normal distribution.
Formula:

a) P(x > 120)


Calculation the value from standard normal z table, we have,  

b) P(x between 100 and 110)


c) P(x < a) = 0.25

Calculation the value from standard normal z table, we have,
