According to a popular wedding website, the average amount spent on flowers for a wedding in the U.S. is $750. To investigate whether the mean amount spent is actually less than the reported average, the mean and standard deviation of the amount spent on flowers from a random sample of 30 recent weddings in the U.S. was obtained. A one-sample t-test resulted in a p-value of 0.065. What conclusion should be made at the 0.05 level of significance? (A) There is convincing statistical evidence to suggest the mean amount spent on flowers for weddings in the U.S. is less than $750. (B) There is convincing statistical evidence to suggest the mean amount spent on flowers for weddings in the U.S. is $750. (C) There is convincing statistical evidence to suggest the mean amount spent on flowers for weddings in the U.S. is greater than $750. (D) There is not convincing statistical evidence to suggest the mean amount spent on flowers for weddings in the U.S. is less than $750. (E) There is not convincing statistical evidence to suggest the mean amount spent on flowers for weddings in the U.S. is $750.
