According to a Pew Research Center nationwide telephone survey of adults conducted between March 15 and April 24, 2011, 55% of college graduates said that college education prepared them for a job (Time, May 30, 2011). Suppose this result was true of all college graduates at that time. In a recent sample of 1850 college graduates, 60% said that college education prepared them for a job. Is there significant evidence at a 2% significance level to conclude that the current percentage of all college graduates who will say that college education prepared them for a job is different from 55%? Use both the p-value and the critical-value approaches. Round your answers for the observed value of z and the critical value of z to two decimal places, and the p-value to four decimal places. Enter the critical values in increasing order.zobserved =Enter you answer; z_observed p-value =Enter you answer; p-value Critical values: Enter you answer; Critical value 1 and Enter you answer; Critical value…
1. Lumber companies dry freshly cut boards in kilns before selling them. As a result of the drying process, a certain percentage of the boards crack. The current drying procedure is known to produce cracks in 16% of the boards. The drying supervisor wants to test a new method to determine if fewer boards will crack. (a) State appropriate hypotheses for a significance test in this setting. To investigate, he selected an SRS of 50 boards, dried them using the new method, and found 5 that cracked (p =5/50 =0.10). To detemine if these data provide convincing evidence that less than 16% of the boards will crack when using the new method, 100 trials of a simulation were conducted. Each dot in the graph below shows the proportion of boards that cracked in a random sample of 50 boards, assuming that each board has a 16% chance of cracking. 0.05 0.15 02 0.25 0.1 Simukated sample proportion of boards that cracked (b) Use the simulation results to estimate the P-value of the test.
