2. En un convivio escolar, se contrató a un taquero que servia tantos tacos como quisiera cada alumno. Cada vez que salía una orden, el mesero anotaba el número de tacos que se pedia: Datos: \( 4,5,2,3,4,3,4,2,3,6,7,3,4,5 \) Se quiere calcular el rango, varianza y desviación estándar de estos datos. Datos: Rango: Varianza:

According to a recent study annual per capita consumption of milk in the United States is 22.6 gallons. Being from the Midwest, you believe milk consumption is higher there and wish to test your hypothesis. A sample of 14 individuals from the Midwestern town of Webster City was selected and then each person's milk consumption was entered into the Microsoft Excel Online file below. Use the data to set up your spreadsheet and test your hypothesis. Gallons of milk- \( 24.6,23.84,25.25,21,17.52,19.61,19.83,26.18,34.97 \), \( 29.9,28.59,20.57,26.94,27.24 \) At \( \boldsymbol{\alpha}=\mathbf{0 . 0 5} \), test for a significant difference by completing the following. Calculate the value of the test statistic ( 2 decimals).

Gallons of milk- \( 24.6,23.84,25.25,21,17.52,19.61,19.83,26.18,34.97 \), \( 29.9,28.59,20.57,26.94,27.24 \) At \( \alpha=0.05 \), test for a significant difference by completing the following. Calculate the value of the test statistic ( 2 decimals). What is the p-value?

Without wait tracking system- \( 24,67,17,19,31,43,12,23,17,37 \) With wait tracking system- \( 31,12,13,18,12,37,9,14,12,16 \) What are the variance and standard deviation of patient wait times for offices with a wait tracking system? What are the variance and standard deviation of patient wait times for visits to offices without a wait tracking system? Please round the answers to 2 decimal place.
