A machine in the student lounge dispenses coffe. The average cup of coffee is supposed to contain 7.0 ounces. A random sample of nine cups of coffee from this machine show the average content to be 7.4 ounces with a standard deviation of 0.70 aunce. Do you think that the machine has slipped out of acjustment and that the average amount of coffee per cup is diferent from 7 cunces? Use a S% level of significance. What are we teting in this problem? O singie proportion (a) What is the level of significance? State the null and aitemate hypotheses. O Hg: -7, H: <7 O Ho: p-7, H: p>7 O Hi-7, H >7 O Ha: - 7; Hạ: + 7 O Họ: p - 7; Hạ:p<7 (b) What sampiling distribution will you use? What assumptions are you making? O The standard normal, since we assume that x has a normal distribution with knowne. O The Student's t, since n is large with unknown e. O The standard nomal, since we assume that x has a normal distribution with unknown. O The Student's t, since we assume that x has a normal distribution with unknown e.
