A webassign.net A machine in the student lounge dispenses coffee. The average cup of coffee is supposed to contain 7.0 ounces. A random sample of six cups of coffee from this machine show the average content to be 7.3 ounces with a standard deviation of 0.60 ounce. Do you think that the machine has slipped out of adjustment and that the average amount of coffee per cup is different from 7 ounces? Use a 5% level of significance. What are we testing in this problem? O single mean O single proportion (a) What is the level of significance? State the null and alternate hypotheses. O Ho: p = 7; Hị: p + 7 O Ho: u = 7; H1: µ < 7 O Ho: p = 7; Hị: p > 7 O Ho: µ = 7; H1: µ > 7 Ο H: μ = 7; H1: μ +7 O Ho: p = 7; Hị: p < 7 (b) What sampling distribution will you use? What assumptions are you making? O The Student's t, since we assume that x has a normal distribution with unknown o. O The standard normal, since we assume that x has a normal distribution with known o. O The standard normal, since we assume that x has a normal distribution with unknown o. O The Student's t, since n is large with unknown o. What is the value of the sample test statistic? (Round your answer to three decimal places.) (c) Find (or estimate) the P-value.
