Answer:
The probability that exactly 6 transactions will be made at an ATM in the next 20 minutes = 0.06306 = 0.0631 to 4d.p
Step-by-step explanation:
This is a Poisson distribution problem
The Poisson distribution formula is given as
P(X = x) = (e^-λ)(λˣ)/x!
where λ = mean = 10 transactions per 20 minutes
x = variable whose probability is required = 6 transactions in the next 20 minutes
P(X = 6) = (e⁻¹⁰)(10⁶)/6! = 0.06306
Since the person didn't write the answer choices they were:
A. On average, city A was warmer than city B.
B. The median and mode are different for city B.
C. The temperature range between the maximum and minimum values for city A is greater than the temperature range between the maximum and minimum values for city B.
D. The median is less for city A than for city B.
I believe it is A personally cause i took the test and got it right
