You own a small storefront retail business and are interested in determining the average amount of money a typical customer spen
Inga [223]

Answer:

Step-by-step explanation:

Hello!

The Confidence intervals for the population mean to follow the structure "point estimation"±" margin of error"

You as the store owner took a sample to determine the average amount of money a typical customer spends on your shop.

n= 26 customers.

X[bar]= $77.506

S= $11.0714

Assuming the variable X: the amount of money spent by a typical customer has a normal distribution and that there is no information about the population standard deviation, the best statistic to use for this estimation is a Students-t:

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

t_{n-1; 1-\alpha /2}= t_{25; 0.995}= 2.787

The margin of error of the interval is:

d= t_{n-1;1-\alpha /2} * \frac{S}{\sqrt{n} }

d= 2.787 * \frac{11.0714}{\sqrt{26} }

d= 6.051

I hope it helps!
