I find the stapling feature for the photocopier in our dept to be not very reliable. The industry standard is that only 2% of items should be stapled incorrectly. In a sample of 120 handouts made for a course, 6 were badly stapled.(a)At a 0.025 significance level using the critical value approach, test to see if the % error is higher than the industry standard. Clearly state your hypothesis and conclusions. (b) How many incorrectly stapled handouts would have to be in the sample of 120 for you to change your conclusion in (a)? Round to whole handouts? (c) If the true % of errors for the copier is 2.5%, calculate the probability of making a type II error for your test in part (a).

Listeners could hear the following musical instruments: guitar, drums, and bass guitar with vocals. The first few seconds from the start until about 8 seconds, listeners would hear only one musical instrument, the guitar at the background which starts soft and melodic with regular beats and rhythmic patterns. At the start of the 8th to 9th seconds, listeners are given the chance to hear the vocals with accompanying instruments that included the drums and the bass guitar. The first few verses of the song were completed within 30 seconds and then, a louder drum instrument started in the 39th second with accompanying vocals that says: “Yeah, Yeah, Yeah, Yeah” two times.

The second set of verses started in 1 minute 4 seconds, again with vocals and a more softer accompaniment of musical instruments (guitar, bass, and drums) and lasted until about 1 minute 34 seconds, again, exactly 30 minutes in regular rhythmic pattern before going to the “Yeah, Yeah, Yeah, Yeah” vocals (1 minute 35 seconds to 1 minute 57 seconds). After this phase, the refrain portion started with louder vocals and musical background starting with “I like it I’m not gonna crack…” and returns to this phrase after repeating the refrain twice (ending after two minutes 29 seconds). A brief space of musical instruments in bass, drums and guitar ensued (2 minutes 33 seconds up to 2 minutes 40 seconds) after the refrain in preparation to the third set of verses where the lyrics of the first verses were apparently repeated. Likewise, at 3 minutes 34 seconds the refrain was also repeated and ended abruptly at about 4 minutes and 10 seconds with the last beat from the vocals and the drum.

The musical elements that were predominantly heard were distinctive of rock music with a lot of accompanying drums and bass guitars and the melody was more than average verging to increasingly loud crescendos, especially during the refrain.
