5.) According to the packaging, 85% of a particular seed will germinate in 5 days or less. Out of 50 seeds, 40 germinated in 5 days or less. At a = 0.05, is there evidence that proportion of seeds that germinate has decreased? (P-value method) State the null/alternative hypotheses Set-up "RECIPE" for the test value and calculate. Find the exact p-value. 4 pts Proper labels 2 pts
