Suppose you take a simple random sample of size n=175 from the population of Reese's Pieces, still assuming that 45% of this pop
ulation is orange (LaTeX: \piπ=.45).
What is the probability that a sample proportion of orange candies will be between .35 and .55?
1 answer:
Answer:
The probability is 
Step-by-step explanation:
From the question we are told that
The sample size is n = 175
The population proportion is p = 0.45
Generally the mean of the sampling distribution is 
Generally the standard deviation is mathematically represented as

=> 
=> 
Generally the probability of that the sample proportion of orange candies will be between 0.35 and 0.55 is

=> 
Generally 
So

=> 
From the z-table

and

So
