State hypothesis

Define test, one or two sided?

Test assumptions (equal variance, normality)

State test statistic (t, F, Chi-square)

State critical value (1 or 2 sided, degrees of freedom)

State conclusions.

Glucose tolerance tests

Researchers compare glucose concentrations in control old and dementia patients. Available data include:

patient	n	mean	median	SD	SE of mean
dementia	37	8.7	9	2.03	0.33
control	42	11.36	11	2.33	0.36

Is there a difference in glucose concentrations? Perform a complete hypothesis test.
