A soda vending machine was designed to discharge an average of 7 fluid ounces per cup. In a test of the machine, ten cups of liquid were taken out of the machine and measured. The mean and standard deviation of the ten measurements were 7.151 ounces and .15 ounces, respectively. Do these data present sufficient evidence to indicate that the mean discharge differs from 7 ounces? a) In the space below write the value of the test statistic Answer for part 1 b) Then write the null hypothesis H0: p = Answer for part 2 c) Indicate what type of test should be done for the alternative hypothesis Answer d) Select the correct answer with α = 0.07 Una máquina expendedora de gaseosas fue diseñada para descargar en promedio 7 onzas de líquidopor taza.
