Answer:
The value is
Step-by-step explanation:
From the question we are told that
The population proportion is
The sample size is n = 343
Generally given that the ample size is large enough , i.e n > 30 then the mean of this sampling distribution is mathematically represent
Generally the standard deviation is mathematically represented as
=>
=>
Generally the the probability that the sample proportion will differ from the population proportion by less than 4% is mathematically represented as
=>
From the z table the area under the normal curve to the left corresponding to 1.887 and - 1.887 is
and
So
=>
Answer:
Probability = 0.1587
Step-by-step explanation:
The provided information is:
Let X be the scores of the IQ test for adults that is normally distributed with mean = 100 and standard deviation
= 15.
Also, US military has minimum IQ score of 85.
Thus, the probability that randomly selected adult does not meet US military enlistment standards is:
The probability can also be written as:
Thus,
Using the Normal probability table probability of Z = -1 is 0.1587
Thus, the required probability is 0.1587
