Answer:
Step-by-step explanation:
Given p + 1 = 2
→ 1 = 2
- p



The above equation is quadratic in p.
p = [ -(-1) ±
] ÷ 2
p = [1 ±
] ÷ 2

Answer is D - $45.75
Step-by-step explanation:
(6 x $4.25) + (3 x $6.75) = $45.75
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.
