Interpret Poisson test technology output - official syllabus scenario

Read the official-HL feature being tested first. Technology output for a environmental sensor Poisson mean test gives p-value 0.076. At the 5% level, state 1 if \(H_0\) is rejected, otherwise state 0. Enter the requested value and choose the interpretation that matches the result.

Worked practice: result and interpretation

Calculate the requested result first, then choose the interpretation that follows from it.
