PART III. Hypothesis Testing

1. Use the following information from an Independent Samples t Test to investigate whether people with a regular healthcare provider visit healthcare providers more often than those who do not have a regular provider. The mean number of visits for respondents with a regular provider is 3.18 and the mean number of visits for respondents without a regular provider is 1.51. Set alpha at .01.

a. State the null and research hypotheses:

H₀:

H₁:

a. Is the F statistic for Levene's test significant?

b. What is the alpha level for the t-test?

c. Obtained t-value:

d. Significance level for the t-test:

e. Decision rule:

If the significance level of the obtained t statistic is greater than ____ (alpha level), we fail to reject the null hypothesis.

If the significance level of the obtained t statistic is equal to or less than ____ (alpha level), we reject the null hypothesis.

f. Decision: Since the significance level of the obtained t statistic is _____ and it is __________(greater or less) than ____ (alpha level), we ________(reject or fail to reject) the null hypothesis.

g. Interpretation/conclusion (Do people with a regular provider use healthcare services more often than those without a regular provider)?
