Professional musicians listened to five violins being played, without seeing the instruments. One violin was a Stradivarius, and the other tour were modern-day violi When asked to pick the Stradivarius (after listening to all five), 44 got it right and 126 got it wrong. Complete parts (a) through (c) below. X = 3.68 (Round to two decimal places as needed.) Find the p-value for this test. p-value = 0.055 (Round to three places as needed.) State your conclusion. Fail to reject the null hypothesis. There is not enough evidence to conclude that the experts are not simply guessing. b. Perform a one-proportion z-test with the same data, using a one-tailed alternative that the experts should get more than 20% correct. Use a significance level of 0.05. State the hypotheses. A. Ho: The percentage is 20%. Ha: The percentage is greater than 20%. B. Ho: The percentage is 20%. Ha: The percentage is not 20%. O C. Ho: The percentage is not 20%. Ha: The percentage is 20%. AO D. H,: The percentage is greater than 20%. H: The percentage is 20%. Find the test statistic for this test.

Statistics teacher realize that his students keep using cell phones during the class. Then he did some research and found out that people use cell phones for 7.2 hours per day on average, and usage time variability around that average is 2.0449. Then he decides to give an assignment of reading books as an alternative of cell phone usage in exchange of 50 extra credit to their statistics exam. After the exam, he collected the data of cell phone usage time from his 127 students and calculated the average cell phone usagetime drops to 6.8 hours per day. a) Under the assumption that probability of uncontrolled factors leading you the wrong statistical decision is five percent, conduct the statistical analysis to decide wheter decrease in the cell phone usage time is real or it happens just because of the random chance b)and interpret the results
