For everything that is plus or subtraction in front of the parenthesis you put a one. so 2+(1)(a+8) so in reality I would believe it is 3(a+8) so 3a+11 for 1.

The heights in inches of males in the united states are believed to be approximately normally distributed with mean u the mean h

vovikov84 [41]

Answer:

Standard error = 0.83

Step-by-step explanation:

Given that the heights in inches of males in the united states are believed to be approximately normally distributed with mean u

Sample mean for 25 adults randomly taken =

$\bar x = 69.72$ inches

Std deviation of sample s = $4.15$ inches

Since X the height of males is Normal we find that the sample mean also will follow a normal distribution.

By central limit theorem, mean of x would be= sample mean= 69.72

Std error = $\frac{s}{\sqrt{n} } =\frac{4.15}{5} \\=0.83$

Standard error of the mean = std dev/square root of sample size.

Here only sample std deviation is known

So we used it

Standard error = 0.83
