Question
one hundred adults who had their Type 1 or
Type 2 diabetes were selected to determine if
the inhalable version of insulin is able to
manage blood sugar levels just as swell as
injected insulin. The adults uses the inhaler for
3 months and then their blood sugar levels
were recorded. Then they uses the injection
for 3 months and then their blood sugar levels
were also recorded. If we want to test if there
is a difference in average blood sugar levels
using the two methods.
Which inference procedure should we use
[Hint: test statistics ]?
O A. None of these
O B. Confidence interval about the
population mean of the secondgroup
C. t-test about the difference between two
means for independent samples.
O D. t-test about the mean difference for
paired samples.
O E. Confidence interval about the population
mean of the first group
