QUESTION 11 Questions 10 - 14 concern the following idea: A tea merchant has customers who want more tannin in their tea for a more bitter flavour. She developed a new blend of tea leaves which she believes will increase the amount of tannin that is released into a cup of tea brewed for 3 minutes. With the previous blend there was an average of 103mg of tannin in a cup of tea. She randomly selected 60 samples of the new blend of tea and brewed them for 3 minutes each, and measured the tannin levels in each cup of tea. These samples gave a mean of x = 104.9mg and a standard deviation of S = 6.2mg Suppose after a t-test was performed, we calculated a p-value of 0.0104, what would be the correct decision in this case (using a = 0.05)? O a. At the 5% level of significance, there is significant evidence to reject H1 and accept Ho- O b. At the 5% level of significance, there is not significant evidence to reject Ho. O c. At the 5% level of significance, there is significant evidence to reject Ho and accept H1. O d. At the 5% level of significance, there is not significant evidence to reject H1.QUESTION 12 Questions 1|] 14 concern the following idea: Atea merchant has customers who want more tannin in their tea for a more bitter avour.
