Obtain the value of the random variable X if the Z-score equals 1.80.
The value of the random variable X if the Z-score equals 1.80 is obtained below as follows:
Let X denotes the random variable with the population mean of 100 and standard deviation of 20.
That is, μ=100, σ=20.
The required value of X is,
z=Xμσ
1.80=X10020
X100=1.80×20=36
X=100+36=136
The value of the random variable X if the Z-score equals 1.80 is 136.

Chances: Risk and Odds in Everyday Life, by James Burke, reports that only 2% of all local franchises are business failures. A Colorado Springs shopping complex has 137 franchises (restaurants, print shops, convenience stores, hair salons, etc.). Let r be the number of these franchises that are business failures. Explain why a Poisson approximation to the binomial would be appropriate for the random variable r. What is n? What is p? What is λλ (rounded to the nearest tenth)?
