A study of bubble behavior in subcooled flow boiling was conducted. In that study, the bubble density (liters per meters squared) was modeled as a function of mass flux (kilograms per meters squared per second) and heat flux (megawatts per meters squared) using the accompanying data.

b. Fit the interaction model, part

a,

to the data using statistical software. Give the least squares prediction equation. Select the correct choice and fill-in the answer boxes.(Round to one decimal place as needed.)
