The quality inspector sampled 38 cups of bubble tea from a tea store and found the average sugar content is 7.832g and standard deviation is .977. Based on the standard making of bubble tea, a cup of bubble tea should have 7.8g of sugar. Can we infer at alpha = .05 the bubble tea's sugar content meets the requirment? (Solve using Z value and P value methods).
