When the program was assessed in a particular region, it was found that of the 219 randomly selected participants, 22 were 5 years old, 107 were 4 years old, 46 were 3 years old, 44 were under 3 years old. Perform a test to see if there sufficient evidence at a-0.01 that the region's proportions differ from the national proportions. The correct hypotheses are: O Ho: The regional distribution is a good fit to the national distribution. HA: The regional distribution is not a good fit to the national distribution.(claim) O He: The regional distribution is not a good fit to the national distribution. HA: The regional distribution is a good fit to the national distribution.(claim) OH: The regional distribution and the national distribution are independent. HA: The regional distribution and the national distribution are dependent. (claim) He: The regional distribution and the national distribution are dependent. HA: The regional distribution and the national distribution are independent. (claim) The test value is The p-value is (round to 3 decimal places) (round to 3 decimal places)
The correct decision is to O reject Ho O do not reject Ho The final conclusion is O There is enough evidence to reject the claim. O There is not enough evidence to reject the claim.

Perform a test to see if there is sufficient evidence at a-0.01 to see if these differ from the governments statistics. 12 The correct hypotheses are: Ha: The sample is a good fit to the Bureau of Transportation Statistics. HA: The sample is not a good fit to the Bureau of Transportation Statistics. (claim) OH: The sample is not a good fit to the Bureau of Transportation Statistics. HA: The sample is a good fit to the Bureau of Transportation Statistics. (claim) OH: The sample and the Bureau of Transportation Statistics are independent. The test value is HA: The sample and the Bureau of Transportation Statistics are dependent. (claim) He: The sample and the Bureau of Transportation Statistics are dependent.. HA: The sample and the Bureau of Transportation Statistics are independent.(claim) The p-value is (round to 3 decimal places) (round to 3 decimal places)
