This article explains how to make tests of hypothesis about experiments with more than two possible outcomes (or categories). Such experiments‚ called multinomial experiments‚ possess four characteristics. Note that a binomial experiment is a special case of a multinomial experiment. An experiment with the following characteristics is called a multinomial experiment. 1. It consists of n identical trials (repetitions). 2. Each trial results in one of k possible outcomes (or categories)‚ where k

of squirrels‚ S. beecheyi and S. variegatus‚ in order to evaluate if SSA can be deemed as a species specific type of behavior. My hypothesis was that squirrels applied the snake skin scent to specific parts of their body in an organized manner. The null hypothesis is that squirrels apply the snake skin scent randomly to parts of their body. My prediction of my hypothesis was that squirrels apply the snake skin scent to body parts that they find prove to be advantageous when trying to escape their

Question: What do you think will happen to a gummy bear when you put it in water over night? Research Hypothesis: The gummy bear will dissolve in the water due to the fact that most gummy bears are made out of pure sugar. Also that since gummy bears are sugar and sugar usually dissolves in water. Also it will vary due to the amount of water that is used in the experiment. Null Hypothesis: The amount of sugar in the gummy bears and the amount of water that is used will have no effect on what

ppm. After that point‚ the number of fish declines slightly. • Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. When the dissolved oxygen levels increase‚ the number of fish that I observed will also increase until you reach 12 ppm. • What would your experimental approach be to test this hypothesis? A few of the ways that I approached this question. Some options

Adjusted Concentration of Hydrogen Peroxide on the change in reaction rate of liver catalase. Hypothesis: Null Hypothesis: If the concentration of the Hydrogen Peroxide is changed then there would be no change in the reaction rate. Alternate Hypothesis 1: I there is an increase in concentration in concentration of Hydrogen Peroxide then the reaction rate of the liver catalase will increase. Alternate Hypothesis 2: If there is an increase in concentration in concentration of Hydrogen Peroxide then the

moderately-intense cardiovascular exercise‚ showing that caffeine will alter the mean change in pulse and respiration to a significant degree Method See School of Biological Sciences (2010) Results The results were obtained by testing the null hypotheses on both the mean change in pulse rate and the mean change in respiration rate‚ using raw data to create graphical representations of the two-tailed‚ two-sample assuming unequal T-tests (for working out of the T-test and the collected raw

trigger separation. -Necromones trigger necrophoric (organisms remove their dead) or necrophobic (organisms avoid their dead) behavior. -Arthropods use pheromones‚ this includes sowbugs and cockroaches. Chemical signals are picked up by antennae. II. Hypothesis: When given a choice between two identical shelters‚ sowbugs will display necrophobic behavior by aggregating in the shelter that does not contain oleic acid. III. Biological Rationale: -C.D. Rollo study showed that cockroaches display necrophobic

et al. 2012). With this information‚ an experimental hypothesis can be formed that the presence of light will cause the redox activity of the spinach chloroplasts to increase‚ while the absence of light will cause this activity to decrease. One possible null hypothesis could be that there will be no significant difference in redox activity between spinach chloroplasts that are under light and in the dark. Therefore‚ the alternative hypothesis must be that there will be a difference in this activity

(2) How would you test if sales in the third quarter are significantly different from those in the fourth quarter? Write down the null hypothesis and decide whether you need to do a t or an F test.
