A tech company wishes to study the number of production facilities that rely on new technologies, like 3D printers. Let the mean number of 3D printers used in a facility be μ. If the tech company wants to know if the number of 3D printers is, on average, less than 9 3D printers per facility, what are the null and alternative hypotheses? Select the correct answer below: H0: μ=9; Ha: μ≠9 H0: μ=9; Ha: μ>9 H0: μ<9; Ha: μ=9 H0: μ=9; Ha: μ<9
