can you help me with this?

7 : Invertase is an enzyme that may aid in spore germination of the fungus Colletotrichum graminicola. A botanist incubated 7 specimens of the fungal tissue in petri dishes and found the sample mean invertase activity to be 520 units with standard deviation 13.5 units. We want to test the hypothesis that the mean invertase activity under these experimental conditions is greater than 510 units. Find the p-value. Assume that the population is normally distributed. (Round your test statistic to two decimals before determining the p-value.) (A) p-value 0.1 (D) 0.05
