Suppose that a manager is interested in estimating the average amount of money customers spend in her store. After sampling 36 t
ransactions at random, she found that the average amount spent was $ 35.25 35.25 . She then computed a 95 95 % confidence interval to be between $ 31.84 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
Answer: The managers statment would most likely give the valid interpretation.
Step-by-step explanation: If the store manager is 95% confident that the average amount spent was between $31.84 and $38.66. Then the store manager is most likey correct so I would have to say I agree with the manager. This may be a tricky question at first, but look at the problem from a different perspective. I am very sorry if this happens to be wrong.
The Principle of Zero Products states that if the product of two numbers is 0, then at least one of the factors is 0. (This is not really new.) If ab = 0, then either a = 0 or b = 0, or both a and b are 0.
