Prof. K. gathered a sample of the amount of time 30 people spent waiting on line for a coffee at the local Fivebucks coffee shop to test the claim that the average wait was less than 10 minutes. The 30 wait times had an average of 5.5 minutes with a standard deviation of 3.25 minutes. Use a 0.05 level of significance to test the claim. What are the following values? n = Do not round this number s = Do not round this number ? = Do not round this number x¯ = Do not round this number ? = Do not round this number Test statistic: Round this number to 2 decimal places. P-value: Report this answer as a decimal rounded to 3 significant figures. DO NOT USE SCIENTIFIC NOTATION! Is the test statistically significant? Type Yes or No
