Question 295479: a random sample of 100 oranges is gathered and the mean diameter obtained was 7.20. If another sample of 100 oranges itaken, what is the probability that its sample mean will be greater than 7.10 inches Answer by stanbon(75887) (Show Source):

----------
t(7.10) = (7.10-0.20)/[s/sqrt(100)]
---
You would have to know "s" to find this t-value.
Then P(x > 7.10) = P(t > "that t-value" when df = 99)
