The average age of all students at a certain college is 22 years and the standard deviation is 2 years. What is the probability

Marianna [84]

Answer:

The probability that the average age of a randomly selected sample of 100 students will be less than 21.8 years is 0.159

Step-by-step explanation:

According to the given data we have the following:

mean = μ= 22

standard deviation = σ = 2

n = 100

μx = 22

σx=σ/√n=2/√100=0.2

Therefore, P( x < 21.8)=P(x-μx)/σx<(21.8-22)/0.2

=P(z<-1)

= 0.159

The probability that the average age of a randomly selected sample of 100 students will be less than 21.8 years is 0.159

I need to know how to simplify this equation

ArbitrLikvidat [17]

$\frac{ {3}^{x + 4} - {3}^{2x + 2} }{ {3}^{x - 2} \times {3}^{x + 4} } = \frac{x + 4 - 2x - 2}{(x - 2) \times (x + 4)} = \frac{ - x + 2}{ {x}^{2} + 4x - 2x - 8 } = \frac{ - x + 2}{ {x}^{2} + 2x - 8}$
i could be wrong, was kinda in a rush
