Use of Secondary data

Both datasets are household surveys for a country where first administrative tier is province and second is district. The respondent households are different in both datasets. The data collection methodology was based on sampling such that in case of dataset A sample is representative at district level and dataset B sample is representative at province level (cannot be disaggregated at district level).
My question is if I can use some statistical technique to infer district level variables from B and use them with other variables provided in A. To explain, let both A and B have variables on household size, income, etc. but only B has variables on household expenditure. So can somehow this information on expenditure variables be utilized with other dataset A that is representative at district level. Also if this is possible please also explain how to use weights in this scheme.

Now I want to check whether the bias of the estimator based on new design is significant.

The formula of the variance of the estimator based on new design is intractable.

How can I check the significance of bias of the estimator based on new design?

Sample 1(Age)
32,28,36,42,29,30,31,35,26
Sample 2(Age)
22,18,22,25,24,19,24,29,36

It is thought that sample 1 is older in this population. What test is appropriate to five evidence for this assumption. State the null/alternative hypothesis and give the test statistic and p-value

Question 2

30 year old males do not exercise as much as 30 year old female. 50 people were asked the frequency of exercise.
Female / Male
Daily 6 / 6
once a week 15/16
once a month 3 / 4
Give the hypothesis, test statistic, analysis

These are the two questions that I am really stuck with. Any help is appreciated.
