A new soft drink is being market tested. It is estimated that 60% of consumers will like the new drink. A sample of 96 taste tested the new drink. a) Determine the standard error of the proportion b) What is the probability that more than 75% of consumers will indicate they like the drink

a

b

Step-by-step explanation:

From the question we are told that

      The population  

       The  sample size is  

       The  sample proportion is  

Generally the standard error is mathematically represented as

substituting values    

The  probability that  more  than  75% of consumers will indicate they like the drink is mathematically represented as

 The  z-score is  evaluated as

So  

This value above is obtained from the z-table  

goog may be able to you find that answer

207/8 is the right
