Mr. Takei plans to add a new flavour of mochi ice-cream to his menu at his Japanese restaurant. He prepared two candidates: coconut and matcha (green tea). To gauge which flavour will be more popular among his customers, he randomly selected 100 customers and offered them a complimentary mochi with one of the two flavours. 50 customers were offered the matcha flavour and the other 50 the coconut flavour. Each customer was asked to rate the ice-cream flavour they tried using a scale of 1 - 5, 1 being 'strongly dislike', and 5 being 'strongly like'

1. Mr. Takei ran the t-test,but he forgot at which significant level the test is run. Can you still use this table to test the hypothesis you wrote in (i)? What is your conclusion?

data: rating by flavor

t = 2.64202964, df = 96.57, p-value = 0.000965

alternative hypothesis: true difference in means between group coconut and group matcha is not equal to 0
