The heights in inches of males in the united states are believed to be approximately normally distributed with mean u the mean height of a random sample of 25 american adult males is found to be x=69.72 and the standard deviation s=4.15 what is the standard error of x

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 =

inches

Std deviation of sample s = 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 =

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

all but the second one

step-by-step explanation:

cuz that one goes over 180

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
