Sally reads a newspaper report claiming that 12% of all adults in the U.S. are left-handed. She decides to test this claim. Sally selects a random sample of 55 classmates and finds that 9 were left-handed. Does this provide sufficient evidence that the proportion of lefties in Sally’s school is different than the national figure? Use α = 0.01. Which is the correct conclusion for this test?

Since p-value = 0.319 > 0.01, I fail to reject H 0 . There is not enough evidence to suggest a difference.
