Question 278487
A random sample of 100 oranges is gathered and the mean diameter obtained was 7.20. If another sample of 100 is taken, what is the probability that its sample mean will be greater than 7.10 inches? 
----------
t(7.10) = (7.10-10.00)/[s/sqrt(100)]

Comment: You need the standard deviation of the 1st sample
of 100 oranges to go any further with this problem.
