What is the correct statistical test to use? b. What are the null and alternative hypotheses? H0: H1: c. The test-statistic for this data is χ2 = d. What is the p-value for this sample (correct to 4 decimal places) e. Should the Null hypothesis be rejected or Not? Why? f. State the conclusion of the test in the context of the problem
For the following question, type the solutions to each part of the question in the space provided at the bottom of the question. Make sure you label each part of the question very carefully:
Is there an association between hair color and body type? The table below shows the results of a researcher's observations of randomly selected people.
Blonde | Brunette | Red Head | |
---|---|---|---|
Short and Slender | 78 | 87 | 60 |
Short and Pudgy | 63 | 92 | 68 |
Tall and Slender | 57 | 118 | 71 |
Tall and Heavy | 54 | 95 | 75 |
What can be concluded at the α = 0.01 significance level?
a. What is the correct statistical test to use?
b. What are the null and alternative hypotheses?
H0: H1:
c. The test-statistic for this data is χ2 =
d. What is the p-value for this sample (correct to 4 decimal places)
e. Should the Null hypothesis be rejected or Not? Why?
f. State the conclusion of the test in the context of the problem
