None When should a block design be conducted instead of a completely randomized design (CRD)?Whenever you need to control the effect of some outside variable by bringing it into theexperiment to form blocks.Whenever forming groups at random from all the individuals available for the study cannot bedone.Whenever you don't have enough samples while using a CRD.Never. We should always choose a CRD design when possible.

Step 1:The correct answer is : option 1 Whenever you need to control the effect of some outside…

Answered: When should a block design be conducted…

Snow avalanches can be a real problem for travelers in the western United States and Canada. A very common type of avalanche is called the slab avalanche. These have been studied extensively by David McClung, a professor of civil engineering at the University of British Columbia. Suppose slab avalanches studied in a region of Canada had an average thickness of ? = 66 cm. The ski patrol at Vail, Colorado, is studying slab avalanches in its region. A random sample of avalanches in spring gave the following thicknesses (in cm). 59 51 76 38 65 54 49 6268 55 64 67 63 74 65 79a) Use a calculator with sample mean and standard deviation keys to find x and s.

A biologist wants to determine if different temperatures (15oC, 25oC, or 35oC) and amounts of sunlight (partial or full) will affect the growth of plants. He will test each combination of temperature and sunlight by randomly assigning 15 plants to each of the combinations. What type of sampling is described in this study? one sample paired data two samples more than two samples
