- A _____________ is a procedure for testing a claim about a property of a populationAn education researcher claims that 57% of college students work year-round. In a random sample of 600 college students, 342 say they work year-round. At α=0.01, is there enough evidence to reject the researcher's claim? Complete parts (a) through (e) below.It is claimed that the daily number of New Covid19 cases in a province is more than 250.

- Pleasantville Steel Works stamps/produces O-rings for various metal-workcompanies. The metal-work companies expect the O-rings to have a diameter of30 cm. The machine that makes these O-rings does not always produce each Oring with a diameter of exactly 30 cm (sometimes, metal shards are left behindafter pressing and affect the next O-ring) and consequently, the O-rings can varyslightly.When the machine is working properly, the O-rings made on this machine have amean diameter of exactly 30 cm. The standard deviation of the diameters of allO-rings produced on this machine is always equal to 0.5 mm. The quality controldepartment takes a random sample of 35 such O-rings every week, calculates themean of those diameters for these O-rings, and makes a 99% confidence intervalfor the population mean. If either the lower limit of this confidence interval isless than 29.9500 cm or the upper limit of this confidence interval is greater than30.04 cm, the machine must be stopped and…A laboratory technician measured the breaking strength of each of five kinds of linen threads by using four different measuring instruments, l1, l2, l3, and l4, and obtained the following results (in ounces): l1 l2 l3 l4 Thread 1 20.9 20.4 19.9 21.9 Thread 2 25.0 26.2 27.0 24.8 Thread 3 25.5 23.1 21.5 24.4 Thread 4 24.8 21.2 23.5 25.7 Thread 5 19.6 21.2 22.1 21.1 Perform a two-way analysis of variance, using the 0.05 level of significance for both tests.The 2017 Chapman University Survey of American Fears asked a random sample of 1207 American adults if they believed that aliens had come to Earth in modern times, and 26% responded yes.
