Suppose that a manager is interested in estimating the average amount of money customers spend in her store. after sampling 36 transactions at random, she found that the average amount spent was $35.25. she then computed a 95% confidence interval to be between $31.84 and $38.66. which statement gives a valid interpretation of the interval? the store manager is 95% confident that the average amount spent by the 36 sampled customers is between s31.84 and $38.66. there is a 95% chance that the mean amount spent by all customers is between $31.84 and $38.66. o there is a 95% chance that a randomly selected customer will spend between $31.84 and $38.66. the store manager is 95% confident that the average amount spent by all customers is between $31.84 and s3866

The store manager is 95% confident that the average amount spent by all customers is between $31.84 and $38.66 .

Step-by-step explanation:

Given : After sampling 36 transactions at random, she found that the average amount spent was $35.25.

She then computed a 95% confidence interval to be between $31.84 and $38.66.

Interpretation: A person can be 95% confident that the true population mean amount spent by all customers is between $31.84 and $38.66.

So, the valid interpretation of the interval would be :-

The store manager is 95% confident that the average amount spent by all customers is between $31.84 and $38.66 .

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

: )

step-by-step explanation: the answer for wha if rt is 10 centimeters long, and wha is st? it’s 6
