The mean height of 10,000 children of age 6 years is 41.26 and standard deviation is 2.24.Find the odds against the possibility that the mean of random sample of 100 is greater than 41.7

Solution:

n_1 = 10,000

\bar x = 41.26

s_1 = 2.24

n_2 = 100

I don't know what should be the hypothesis .........
