Can you differentiate between quantitative and qualitative research proposal?

Depends what you are looking for? With this sort of question it is obvious you are not so sure!

Quantitative Research is used to quantify the problem by way of generating numerical data or data that can be transformed into useable statistics.

Qualitative Research is primarily exploratory research.  It is used to gain an understanding of underlying reasons, opinions, and motivations.

Quantitative Researchis used to quantify the problem by way of generating numerical data or data that can be transformed into usable statistics. It is used to quantify attitudes, opinions, behaviors, and other defined variables – and generalize results from a larger sample population. Quantitative Research uses measurable data to formulate facts and uncover patterns in research. Quantitative data collection methods are much more structured than Qualitative data collection methods. Quantitative data collection methods include various forms of surveys – online surveys, paper surveys, mobile surveys and kiosk surveys, face-to-face interviews, telephone interviews, longitudinal studies, website interceptors, online polls, and systematic observations

Qualitative Research is primarily exploratory research.  It is used to gain an understanding of underlying reasons, opinions, and motivations. It provides insights into the problem or helps to develop ideas or hypotheses for potential quantitative research. Qualitative Research is also used to uncover trends in thought and opinions, and dive deeper into the problem. Qualitative data collection methods vary using unstructured or semi-structured techniques. Some common methods include focus groups (group discussions), individual interviews, and participation/observations. The sample size is typically small, and respondents are selected to fulfill a given quota

Quantitative number of proposals are more but quality is not there. The quality proposal no need more proposals one is enough. That is accurate and specific.
