What is the sex distribution of a population mean?

The sex distribution of a population mean refers to the proportion of males and females within a given population. It is typically expressed as a ratio or percentage, indicating how many males and females are present. This distribution can vary widely depending on factors such as geography, culture, and age demographics. Analyzing sex distribution is important for understanding social dynamics and planning for resources and services.


According to a study conducted in one city 36 of adults have credit card debts more than $2000. A simple random sample of n 200 adults is obtained from the city. Describe the sampling distribution?

The sampling distribution of the sample proportion of adults with credit card debts greater than $2000 can be described using the population proportion, which is 36% (or 0.36). For a simple random sample of 200 adults, the mean of the sampling distribution will be equal to the population proportion (0.36), and the standard error can be calculated using the formula ( \sqrt{\frac{p(1-p)}{n}} ), where ( p ) is the population proportion and ( n ) is the sample size. In this case, the standard error would be approximately ( \sqrt{\frac{0.36(0.64)}{200}} ), leading to a normal distribution centered at 0.36, assuming the sample size is sufficiently large.

What proportion of a normal distribution corresponds to z-scores greater than plus 1.04?

To find the proportion of a normal distribution corresponding to z-scores greater than +1.04, you can use the standard normal distribution table or a calculator. The area to the left of z = 1.04 is approximately 0.8508. Therefore, the proportion of the distribution that corresponds to z-scores greater than +1.04 is 1 - 0.8508, which is approximately 0.1492, or 14.92%.

The proportion of the population that holds one opinion compared to those with opposing opinions or no opinion is referred to as the opinion ratio or distribution.

What is the relation occupational structure and development?

The distribution of the population according to the different types of occupations is referred to as the occupational structure. Occupations are generally classified as primary (agriculture, mining, fishing, etc.), secondary (manufacturing industry, building and construction work, etc.) and tertiary (transport, communications, banking, etc.). The proportion of people working in different activities reflects the economic development of a country. Developed nations have a high proportion of people in secondary and tertiary activities. Developing countries tend to have a higher proportion of their workforce engaged in primary activities.
