1. Is race a factor in the number of times a month a person eats out? The table below shows data that was collected.

Asian	White	Black	Hispanic
10	4	1	15
7	4	10	2
13	7	11	1
8	8	7	11
6	7	11	5
13	0	2	0
13	13	13	1

Assume that all distributions are normal, the four population standard deviations are all the same, and the data was collected independently and randomly. Use a level of significance of=0.05=0.05. H0:1=2=3=4H0:1=2=3=4 H1:At least two of the means differ from each other.

1. For this study, we should useSelect an answer:

GOF-Test

2-SampTInt

2-PropZTest

2-PropZInt

T-Test

1-PropZTest

-Test

1-PropZInt

Interval

ANOVA

2-SampTTest

1. The test-statistic for this data =_____(Please show your answer to 3 decimal places.)
2. The p-value for this sample =_______(Please show your answer to 4 decimal places.)
3. The p-value isSelect an answer:

less than (or equal to) alphag

greater than alpha

1. Base on this, we shouldSelect an answer:

reject the null hypothesis

accept the null hypothesis

fail to reject the null hypothesis

1. As such, the final conclusion is that...
   • There is sufficient evidence to support the claim that race is a factor in the number of times per month people eat out.
   • There is insufficient evidence to support the claim that race is a factor in the number of times per month people eat out.

1. A hospital wants to determine if the type of treatment for pneumonia is a factor in recovery time? The table below shows the number of days to recovery for several randomly selected pneumonia patients that had various types of treatment.
