An experiment was conducted to assess the effect of baking temperature on the density of bread. A large batch ofwhite bread dough and a large batch of whole wheat bread dough were prepared. Each of the batches was formedinto loaves, resulting in a total of loaves. Each of the white bread loaves was randomly assigned to one ofthree baking temperatures (low, medium, and high), so that loaves were baked at the low temperature, werebaked at the medium temperature, and were baked at the high temperature. A similar process of randomassignment was carried out for the whole wheat bread loaves.Which of the following are the treatments in the experiment? (A) The loaves of bread(B) The type of bread (white, whole wheat)(C) The density of the bread(D) The baking temperatures (low, medium, high)(E) The two batches of bread dough

A neuroscientist is interested in testing the effects of environment on dendritic branching in the hippocampus (dendrites increase the receptivity of neurons and may be an important basis of cognition). To test this, he took one group of rats (n = 11) and housed them in an “enriched” environment (consisting of a large box with tunnels to run through, toys to play with, etc.) and then he took another group of rats (n = 11) and housed them in an “isolate” environment (rats were housed alone without any tunnels or toys). After 6 weeks, the number of dendritic spines in a particular region of the hippocampus from these rats was imaged and counted. The results are below. Did the different housing conditions have an effect on the number of dendrite branches? Solve using the steps in hypothesis testing. Enriched condition Isolate condition Mean number of dendrites 40 10 (Estimated) Standard Deviation 10 4 Question: Calculate the upper 95% confidence interval…
