Complete Question
Given a population where the probability of success is p= 0.40 calculate the probabilities below if a sample of 300 is taken.
A. Calculate the probability the proportion of successes in the sample will be less than 0.42 (round 4 decimals)
B. What is the probability that the proportion of successes in the sample will be greater than 0.44 (round 4 decimals)
A
B
Step-by-step explanation:
From the question we are told that
The probability of success is p = 0.40
The sample size is n = 300
Generally given that the sample size is large enough n > 30 then the mean for this sampling distribution is
Generally the standard deviation is mathematically represented as
=>
=>
Considering question A
Generally the probability the proportion of successes in the sample will be less than 0.42 is mathematically represented as
=>
From the z table
The area under the normal curve to the left corresponding to 0.7072 is
=>
Considering question B
Generally the probability the proportion of successes in the sample will be less than 0.44 is mathematically represented as
=>
From the z table
The area under the normal curve to the left corresponding to 1.4144 is
=>
