In: Statistics and Probability
A survey asked respondents if they would rather live in a place with a slower pace of life or a place with a faster pace of life. The survey also asked the respondent's gender. Consider the following sample data.
Preferred Pace of Life |
Gender | |
---|---|---|
Male | Female | |
Slower | 230 | 218 |
No Preference | 22 | 26 |
Faster | 88 | 46 |
(a)
Is the preferred pace of life independent of gender? Conduct a hypothesis test using a 0.05 level of significance.
State the null and alternative hypotheses.
H0: The preferred pace of life is not
independent of gender.
Ha: The preferred pace of life is independent
of gender.H0: Preferring a slower pace of life
is mutually exclusive from preferring a faster pace for both
genders.
Ha: Preferring a slower pace of life is not
mutually exclusive from preferring a faster pace for both
genders. H0: The
preferred pace of life is independent of gender.
Ha: The preferred pace of life is not
independent of gender.H0: Preferring a slower
pace of life is not mutually exclusive from preferring a faster
pace for both genders.
Ha: Preferring a slower pace of life is
mutually exclusive from preferring a faster pace for both
genders.
Find the value of the test statistic. (Round your answer to three decimal places.)
Find the p-value. (Round your answer to four decimal places.)
p-value =
State your conclusion.
Do not reject H0. We conclude that the preferred pace of life is not independent of gender.Do not reject H0. We cannot conclude that the preferred pace of life is not independent of gender. Reject H0. We cannot conclude that the preferred pace of life is not independent of gender.Reject H0. We conclude that the preferred pace of life is not independent of gender.
(b)
Discuss any differences between the preferences of men and women. (Round your answers to two decimal places.)
The highest percentages are for ---Select--- a slower no preference in a faster pace of life by both men and women. However % of women prefer a slower pace compared to % of men, and % of men prefer a faster pace compared to % of women. So, women are more likely than men to prefer a ---Select--- slower faster pace while men are more likely than women to prefer a ---Select--- slower faster pace.
H0: The preferred pace of life is
independent of gender.
Ha: The preferred pace of life is not
independent of gender
The highest percentages are for 75.17 SLOWER FEMALE a slower no preference in a faster pace of life by both men and women. However 75.17 % of women prefer a slower pace compared to 67.65 % of men, and 25.88% of men prefer a faster pace compared to 15.86 % of women. So, women are more likely than men to prefer a --SLOWER- slower faster pace while men are more likely than women to prefer a --FASTER- slower faster pace.
