A simple random sample consists of 65 lengths of piano wire that were tested forthe amount of extension under a load of 30 N. The average extension for the 65 lines was 1.102mm and the standard deviation (sample) was 0.020 mm. Let Āµ represent the mean extensionfor all specimens of this type of piano wire.
(a) Assuming a signiļ¬cance level of Ī± = 0.05, determine the critical value for testing
H0 : Āµ ā¤ 1.1 vs HA : Āµ > 1.1.
(b) Find the test statistics and p-value for the previous test. (An approximation of the p-value using a t-table is suļ¬cient)
(c) State the conclusion of the previous test.
