Answer:

The answer is "(27.030,29.770)"

Step-by-step explanation:

$(\bar{x}) = 28.4$

$(n)= 49$

$(\sigma) = 6$

$(CI) = \bar{x}\pm z^*_{\frac{\alpha}{2}} \frac{\sigma}{\sqrt{n}}$

$z^*_{\frac{\alpha}{2}}\ for \ 89\%\ confidence = 1.598 \\\\\text{Using z table }\\\\ NORM.S.INV(1-\frac{(1-0.89)}{2})$

$CI = 28.4 \pm 1.598 \times \frac{6}{\sqrt{49}}=(27.030,29.770)$

What goes outside during division with fractions? The numerator, or the denominator?

Ymorist [56]

Answer:

Denominator

Step-by-step explanation:

Think of it this way - numerator/denominator = nana/dog

Nana goes inside to the bathroom, but the dog goes outside to do its thing

If it was the other way around, it wouldn't be very pleasant.

LOL

Anyway, I hope this was helpful

What’s the difference between numbers that are to the power of with parentheses and no parentheses. For example (-2/5)^3 and -2/

Verdich [7]

Answer:

See below

Step-by-step explanation:

The first one 'cubes' the denominator AND the numerator:

(-2/5)^3 = -2/5 * -2/5 * -2/5 = -8/125

The second one 'cubes' only the denominator:

-2/5^3 = -2 / (5 * 5 * 5) = - 2 / 125
