Six human skulls from around 4000 b.c. were measured, and the lengths have a mean of 94.2 mm and a standard deviation of 4.9

Answer:

Step-by-step explanation:

Hello!

You have to estimate the mean length of 4000 b.c. human skulls trough a 95% confidence interval.

You know that

n= 6 human skulls

$\frac{}{X}$ = 94.2mm

S= 4.9

Assuming that the variable X: length of a 4000b.c. human skull (mm) has a normal distribution, to construct the interval you have to use the t statistic:

[ $\frac{}{X}$ ± $t_{n_1;1-\alpha /2} * \frac{S}{\sqrt{n} }$ ]

$t_{n-1;1-\alpha /2}= t_{5; 0.975}= 2.571$

[94.2 ± 2.571 * $\frac{4.9}{\sqrt{6} }$ ]

[89.06; 99.34]mm

With a 95% confidence level you'd expect the interval [89.06; 99.34]mm to contain the value for the average skull length for humans 4000 b.c.

I hope this helps!

If there are rectangles that all have the same perimeter, which one will have the least area? which one will have the greatest a

hichkok12 [17]

The ones that will have the least area will be the ones that are the thinnest. That is to say, the ones with the greatest width to length (or length to width) ratios would have the smallest area.
The ones with the greatest area would be the ones with the smallest width to length (or length to width) ratios. They would be squares.
