The head start program provides a wide range of services to low-income children up to the age of 5 years and their families. Its goals are to provide services to improve social and learning skills and to improve health and nutrition status so that the participants can begin school on an equal footing with their more advantaged peers. The distribution of ages for participating children is as follows 10% five-year-olds, 41% four- year-olds, 21% three-year-olds, and 28% under three years. When the program was assessed in a particular region, it was found that of the 211 randomly selected participants, 23 were 5 years old, 103 were 4 years old, 53 were 3 years old, 32 were under 3 years old. Perform a test to see if there sufficient evidence at a = 0.05 that the region's proportions differ from the national proportions. The correct hypotheses are: O H: 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 Ho: 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) Ho: The regional distribution and the national distribution are independent. H: The regional distribution and the national distribution are dependent.(claim) O Ho : The regional distribution and the national distribution are dependent. H: The regional distribution and the national distribution are independent. (claim) The test value is (round to 3 decimal places) The p-value is (round to 3 decimal places) The correct decision is to reject Ho O do not reject Ho The final conclusion is There is enough evidence to reject the claim. There is not enough evidence to reject the claim. There is enough evidence to support the claim. There is not enough evidence to support the claim.

Transcribed Image Text:The head start program provides a wide range of services to low-income children up to
the age of 5 years and their families. Its goals are to provide services to improve social
and learning skills and to improve health and nutrition status so that the participants
can begin school on an equal footing with their more advantaged peers. The
distribution of ages for participating children is as follows 10% five-year-olds, 41% four-
year-olds, 21% three-year-olds, and 28% under three years. When the program was
assessed in a particular region, it was found that of the 211 randomly selected
participants, 23 were 5 years old, 103 were 4 years old, 53 were 3 years old, 32 were
under 3 years old. Perform a test to see if there sufficient evidence at a = 0.05 that the
region's proportions differ from the national proportions.
The correct hypotheses are:
O H: 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 Ho: 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)
Ho: The regional distribution and the national distribution are independent.
H: The regional distribution and the national distribution are dependent.(claim)
O Ho : The regional distribution and the national distribution are dependent.
H: The regional distribution and the national distribution are independent.
(claim)
The test value is
(round to 3 decimal places)
The p-value is
(round to 3 decimal places)
The correct decision is to
reject Ho
O do not reject Ho
The final conclusion is
There is enough evidence to reject the claim.
There is not enough evidence to reject the claim.
There is enough evidence to support the claim.
There is not enough evidence to support the claim.
