No. 7.8 is not equivalent to 9.

If you rounded to the nearest whole number, yes, the number that you'd get would be 9 but if you were to look at the two values, 7.8 and 9, then no, these two are not equivalent due to the fact that 9 is 1.2 values higher than 7.8

Answer:

10000*0.6065=6065

A. about 6,065

Step-by-step explanation:

Definitions and concepts

The Poisson process is useful when we want to analyze the probability of ocurrence of an event in a time specified. The probability distribution for a random variable X following the Poisson distribution is given by:

P(X=x) =\lambda^x \frac{e^{-\lambda}}{x!}

And the parameter \lambda represent the average ocurrence rate per unit of time.

For this distribution the expected value is the same parameter \lambda  

E(X)=\mu =\lambda=0.5  , Var(X)=\lambda=0.5, Sd(X)=707

Solution to the problem

We want "how many would have no blemishes" so first we need to find the probability that X=0, since X represent on this case the number of blemishes on each door. And if we use the mass function we got this:

P(X=0) =0.5^0 \frac{e^{-0.5}}{0!}=0.6065

And now since we have a total of 10000 doors painted we can find how many we would expect with no blemishes:

10000*0.6065=6065

A. about 6,065
