antiseptic1488 [7]

Answer:

$\=x=82$

Step-by-step explanation:

From the question we are told that:

Data

$\begin{center}\begin{tabular}{ |c|c|c|c|c|c| } 87& 91& 86& 82& 72&91 \\ 60& 77& 80& 79& 83&96 \end{tabular}\end{center}$

Generally the equation for Point estimate $\=x$ is mathematically given by

$\=x=\frac{\sum_x}{n}$

$\=x=\frac{87 +91+ 86+ 82 +72 +91+ 60+ 77 +80+ 79+ 83 +96}{12}$

$\=x=\frac{984}{12}$

$\=x=82$

Adult male heights have a normal probability distribution with a mean of 70 inches and a standard deviation of 4 inches.

nexus9112 [7]

Answer: 0.84134

Step-by-step explanation:

We need to find the z-score for the given information first since this will help us find the probability. The formula for this is

Z score = $\frac{x - \mu}{\sigma}$

We have

$x =$ 66 inches (the raw score)

$\mu =$ 70 inches (the population mean)

$\sigma$ = 4 inches (the standard deviation)

This gives

Z score = $\frac{x - \mu}{\sigma}$ = $\frac{66-70}{4} = -1$

If you use a calculator, or a Z-score table then P(x > Z) is just P(Z > -1) which gives a probability of 0.84134.
