There are 12 inches in a foot. If he needs 4 feet, and 4 times 12 equals 48, then he needs 4 more inches.
Answer:
The probability that the sample proportion of airborne viruses in differ from the population proportion by greater than 3% is 0.006.
Step-by-step explanation:
According to the Central limit theorem, if from an unknown population large samples of sizes <em>n</em> > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
The standard deviation of this sampling distribution of sample proportion is:

The information provided is:
<em>n</em> = 596
<em>p </em>= 0.09
As the sample size is quite large, i.e. <em>n</em> = 596 > 30, the central limit theorem can be used to approximate the sampling distribution of sample proportion by a Normal distribution.
The mean and standard deviation are:

Compute the probability that the sample proportion of airborne viruses in differ from the population proportion by greater than 3% as follows:


Thus, the probability that the sample proportion of airborne viruses in differ from the population proportion by greater than 3% is 0.006.
