4. A researcher suggests that small doses of hyaluronic acid (HA) will promote the uptake of water in human skin, thus reducing symptoms of dryness and dehydration. He suggests that HA binds to water and prevents it from evaporating off of the skin. The researcher creates a skin cream formulated with HA and compares the skin of 100 people before and after use of the cream. Formulate one null (H) and one alternative (H₁) hypothesis. Describe the data you would expect to see that would support the null hypothesis.
