To find out how many men Bryan should expect to have a beard among the next 90 men, we can use the proportion of men with beards from the previous observation.
From the data:
– 18 men out of 60 had a beard.
First, we can find the proportion of men with beards:
[ text{Proportion} = frac{18}{60} = 0.3 ]
Now, we can apply this proportion to the next 90 men:
[ text{Expected men with a beard} = 0.3 times 90 = 27 ]
So, Bryan should expect about 27 men out of the next 90 to have a beard.
