A recent study showed that in a random sample of 100 people, 30% had visited Worlds of Fun.  In another random sample of 150 people 24% had visited Knott’s Berry Farm. At ∝ = 0.05 are the proportions of people who visited each park different? The samples were independent. In a two sample hypothesis test the p-value was 0.2917.  In this test your decision would be to reject the null hypothesis  fail to reject the null hypothesis  accept the alternate hypothesis as true  none of the above
