If the mean body tempe tire of a bird is 75 degrees with a standard deviation of 4 degrees, which is least likely?

1. A random sample of 50 birds will have a mean body temperate that is less than 72 degrees

2.

a single bird, chosen at random, has a body temperature that is less than 72 degrees.

3. a random sample of 10 birds will have a mean body temperature less than 72 degrees.
