Suppose that a student collects the following spectrophotometric data to determine the relative concentrations of HMR and MR in solution:
The abosorbance at 425 nm was measured to be 0.280 and at 520 nm was 0.720, the slopes corresponding to standard Beer's Law plots were as follows:
| αIA = | 0.072 | αIB = | 0.306 |
| αIIA = | 0.760 | αIIB = | 0.036 |
Using this data, calculate the ratio between the relative concentrations of MR- and HMR in this solution.

Suppose that a student collects the following spectrophotometric
data to determine the relative concentrations of HMR and MR in
solution: The abosorbance at 425 nm was measured to be 0.320 and at
520 nm was 0.600, the slopes corresponding to standard Beer's Law
plots were as follows:
?IA = 0.072 ?IIA = 0.760
?IB = 0.306 ?IIB = 0.036
Using this data, calculate the
ratio between the relative concentrations of MR- and HMR in this
solution.

Suppose that a student collects the following spectrophotometric
data to determine the relative concentrations of HMR and MR in
solution: The abosorbance at 425 nm was measured to be 0.170 and at
520 nm was 0.690, the slopes corresponding to standard Beer's Law
plots were as follows:
αIA = 0.072
αIB = 0.306
αIIA = 0.760
αIIB = 0.036
Using this data, calculate the ratio between the relative
concentrations of MR- and HMR in this solution.

4. Data were collected on student teachers relative to their use
of certain teaching strategies that had been presented to them in
preservice education. There were 28 student teachers who had
learned to use the strategies (9 in 1979, 9 in 1980, and 10 in
1981). In 1978 there were 6 teachers who did not learn to use the
strategies, and they were used as a control group. The investigator
recorded the average number of strategies used per week by...

The U.S. Census Bureau collects data on the ages of married
people. Suppose that eight married couples are randomly selected
and have the ages given in the following table. Determine the 98%
confidence interval for the true mean difference between the ages
of married males and married females.
Let d=(age of husband)−(age of wife)d=(age of husband)−(age of
wife). Assume that the ages are normally distributed for the
populations of both husbands and wives in the U.S.
